Apps in User interface missing

What type of hardware are you using: VPS bought online
What YunoHost version are you running: 12.0.17
How are you able to access your server: The webadmin
SSH
Direct access via physical keyboard/screen

Describe your issue

After I did restore my apps from a different server, I can’t see the apps in the user interface of Yunohost (icons are missing).
Using the subdomain, I can use the apps and they work fine.
I’ve tried to play with permissions and added all permissions to the apps and to a specific user, but that didn’t help. The app icons won’t appear in the user interface.
Both, regular users and users in the admin group are affected by the issue.
When I install a new app, the app icon of that particular app does appear in the user interface. I.e. only the apps restored are missing.
Do you have any idea what I could try?

Share relevant logs or error messages

I don’t see a related issue in the diagnosis and I don’t see errors in the logs. Actually I don’t really know where to look.

Just to be sure, you don’t mean that “just” the icon is missing but the entire app tiles, right ?

Can you confirm that you tested with an admin user connected to the portal ?

yes, the entire tiles are missing.
yes, I did test with the admin user and I can also only see newly installed app tiles

Check in the webadmin >applications >your app, that “Visible as tile in user portal” switch is on.

good point, but the switch is on. Switching off+save and on+save doesn’t change anything.
For newly installed apps that works (tile disappears and re-appears) when I flip the switch.
I’ve also tried backup and restore, but it didn’t help

I’ve just remembered that I’ve also changed the domain for the apps from
subsubdomain.subdomain.domain.ltd
to
subdomain.domain.ltd

I’ve switched back to the first option (with the subsubdomain) and the tile is back in the user interface. :tada:

So switching from subsubdomain to subdomain makes the tile disappear.
Do you happen to know why this is and what can be done about it so that I can change to the subdomain again?
