Only 2 errors (that repeat every once in a while), but the /bcmath does not seem important, the appstore own looks suspicious:

The Bell (notifications) Show Updates, but clicking on link to Apps shows All Apps Up To Date
That is the problem. The bell icon for notifications shows the red-dot and the dialog lists updates for Calendar 4.7.1, Notes 4.10.0, CSS 1.16.0 and Nextcloud 28.0.5, but clicking on the links to go to the apps page to update shown “All Apps Up To Date”.
This is really odd and annoying. Moreover, if I go do different pages in Nextcloud and then loop back to the Apps page (usually 3-4 times), on the 4th or so retry the updates are shown and I can then update apps normally.
Could this be a side-effect of the config.php regression of the missing slash for apps/, /apps/ issue?
I’ve had nextcloud since version 24 or 25 and never had an issue before with the update notification and finding the updates ready to install on the Apps page after clicking the link. Any ides what the issue can be?
