arrange photo albums in chronological order

I don't think so. It seems they are put in order of when you last added images (or the date of the images you last added - Im not totally sure on that), and I am not aware of any way to change this.

Worse, you can drag them to an order, but it will change next time you add images to one of them.

Photos is completely broken... i'm trying to use iCloud photos to sync my devices but i always have issues...

i just got a new iPad and as i activated iCloud photos on it all my albums disappeared from all other devices...

i had to create all my albums again... it is a 15.000 pictures library...

i'm afraid of what will happen when my new iPhone 12 pro max will arrive!

Control (right) - click on the My Albums folder and then select the type of sorting you want the enclosed albums to be sorted by:

When you add a photo to an album, with a date outside the range of the previous photos in the album, the date of the album may change, and the albums may get rearranged. That is normal and the expected behaviour, if the albums have been sorted by the date. It is more stable to sort them by name, because the name of an album does not change automatically.

Yes but when I choose to sort them in alphabetical order they MUST remain that way! And they MUST sync that way to all my iOS devices, but the problem is that for no reason they sync in a mixed order and then on my Mac they mix up... so I have to sort alphabetically again... and again.... and again.... it is sooooo stupid!!!!

Yea but it will not last for long... they will get mixed randomly soon! And you will not know why!
