This shared album is unavailable - iOS Photos sharing album error

I'm on the phone with them now. I've made 5 Shared Albums since then, all with Public links and they all are visible perfectly fine. The Album in question is 11GB and though 143 videos per album is way under the limit, perhaps the 11GB is over and it's an unwritten limitation? I'm getting connected to a Senior Tech because the 1st tier tech had no idea.

The Senior tech wasn't exactly sure either. We kind of surmized that there must be an unwritten storage limitation. So what I'm doing now is making a series of new Shared Albums and only uploading 10 videos at a time. Most of these videos are 5min long or trimmed to 5min since that's the limit. I'm going to continually keep adding videos until the Shared Album Public Link becomes invalid again. The original public link is now gone. Also even with the 143 videos anyone invited with an iCloud account could see the album fine. So, again, it seems like a storage limitation wth the Public link, but also the official Apple Sharing Album limitations do not explicitly say those same limitations are also for Public Shared Albums. But through this testing I will be able to post my findings and what exactly are the Public Shared Album limitations. Stay tuned.

Just uploaded 39 videos totaling about 3GB and it's still failing to load with same error. ***? I have 1TB of iCloud space, Apple please let me determine how I want to use it. I'm going to start removing one video at a time and see when it finally starts working.

Where did you read that? Because the tech said he couldn't find anything about that, we had discussed that also. All the photos/videos would still reside on your own personal iCloud, only the HTML for the Shared Album would reside somewhere else, which means it's only using a tiny bit of space. And if Apple is constricting that why is it not documented anywhere? Even the high tier Apple tech docs said nothing about that either. Not that that's not the case, it's just something we can't verify unless you found it on an official Apple docs page.

Still having varying results with my tests. I had to drop down from 39 to 22 videos and 1.06GB before the page worked, but then added 1 video at a time and it kept working. I got up to almost 2GB and it was still working with 27 videos. So I've now removed all the videos and am uploading 10 videos at a time. It's almost like Apple's server stalls on your Shared Album if you upload too many videos at one time, not sure though, hence the 10 videos at a time test. I'll keep ya posted. Thanks!

Correct. The Tech & I were already aware of those, but those do not report on anything concerning a Shared Album, they only discuss a Photo Stream. He nor I were making wild assumptions since there is apparently no official Apple documentation explaining the limitations of Shared Albums. And my Shared Album is no where close to the iCloud storage limitations as I referenced in my original Post.

More crazy nonsensical testing. I've been uploading in batches of 10, the first 10 worked fine, but after the second 10 the page would no longer load. Ironically I used the exact same 10 videos again to ensure the videos weren't the issue. It's only 1.71GB also, slightly less than my previous test which was almost 2GB and 28 videos. I'm going to start removing videos 1 by 1 till it works again, if it does at all.

It seems we might have an answer finally. It appears that it doesn't matter the number of videos, what matters is the total capacity of those videos. The magic number seems to be 1.5GB. You can have as many videos as you want as long as the total capacity doesn't go over 1.5GB. Very sad. As a parallel test I uploaded all 143 videos to a free Google Photos/Videos account and it didn't have to trim any to Apple's 5min limit and after uploading all 143 videos I was able to make the page Public and the page loaded perfectly with all 143 videos. In fact, I was able to upload all 143 videos in about 3 hours to Google vs the 20+ hours it took to upload all 143 to Apple when this all started. I'm always praising Apple, but this time they lost miserably. Plus, not to mention, that Apple doesn't even speak of this limitation in any of their documentation. Apple makes an iPhone that has the ability to film 4k video, but only gives us 1.5GB to be able to share those videos with the world. Kind of sad. These results are very disappointing, sorry I don't have better news.

I apologize, I was only referring to what we didn't know, the number of videos/photos within a Shared Album and/or the capacity of such a Shared Album, which Apple's limitation documentation does not answer either of those questions. Sorry, I was misleading in my response. And I agree with everything you stated in last response. I'm so boggled as to why we're so limited & why they've done what they've done just like you said too. It just *****.
