iOS 14.1 on iPhone 11 Pro: unable to save changes (markup to a saved screenshot)

Good morning,

Thanks in advance for your help.

After some tests I've been able to narrow the problem down quite a bit.

Device: iPhone 11 Pro

iOS: 14.1

App used: Photos (native)

Description: there seems to be some sort of error when trying to add Markup edits, to a previously saved screenshot. It constantly gives this error: "Unable to save changes – an error occurred while saving. Please try again later" (see photo attached)

• A) It only happens with Markup edits in my tests. You can crop, adjust exposure/contrast/etc, and add filters. Then save. And it works.
• B) It only seems to happen with preexisting screenshots. By this I mean any given screenshot once you have already saved it to the albums. Even if it's only been seconds since the save.

But it doesn't happen when you add Markup edits from the pop-up window that shows when tapping on the screenshot thumbnail showing on the bottom left corner right after taking the screenshot. When you do it from that screen, the Markup edits save without any problem.

Not an easy thing to explain, I hope I did a decent job.

To reproduce:

1) Take a screenshot

2) Save it by:

a) waiting some seconds to let the thumbnail automatically disappear

b) swipe left on the thumbnail

c) tap on the thumbnail -> tap on DONE

3) Go to the screenshot through either the recents/screenshots album

4) Tap Edit -> Tap on ... to show the next menu -> tap on Markup

5) Add any markup edits, as a pencil/marker or a bubble/text

6) tap on DONE to save the changes -> ERROR TRIGGERS
