When I search for Tags and click in the list a Tag, the Tag I clicked on does not appear – it always shows the same results: all entries for 15 October.
I deleted the app, reinstalled it and turned on synchronisation and downloaded the 1,855 entries from the cloud again.
This seems to have solved the problem.
