Hi. I upgraded three Nextclouds to Nextcloud 28.0.2 and there is a bug (see issue 43243 for RC5). Also thanks to @Slem and his thread.
If i set exipration date it is marked as tomorrow 02.02.2024 but i can not change it. I get the error in the screenshot.

If you need expiration date please do not upgrade to Nextcloud 28.0.2.
Hello,
Unfortunately I did upgrade before seeing this … I’m seeing the same exact problem, whatever the date I put, either using the calendar widget or entering it manually. I even tried mm/dd/yyyy in case it was some problem with the date format (in french I have dd/mm/yyyy).
Pierre.
Ugh. I seem to be running into a form of this problem. I have my sharing set up to have a default expiration, but now that value can’t be changed via the “customize link” menu.
You can set a default expiration in admin settings. Hope that helps you.
I have the same problem with 28.0.2. Setting a default expiration date in admin settings makes no difference in my case.
In the 28.0.3 RC1 I can‘t reproduce it.
Release on Thursday, maybe it helps 
On my test system Nextcloud 28.0.3 RC1 there is still the bug. 
It appears to be fixed in NextCloud 28.0.3 web interface but not in the desktop client. The latest desktop client 3.12.1 still has the expiry date is in the past problem.
I have Nextcloud 28.0.3 and I have the Bug on the web interface (we don’t use client).

I just performed an upgrade via OCC ( 28.0.4 it’s available) and the Bug for the web interface it’s fixed.
