Using Enpass 6.10.1 (1661) on Linux Arch (latest version), but same symptom on Linux Debian (latest version)
When selecting a tag or sub tag in left panel, selected tag goes grey, and items with that tag are shown in the panel beside. This is correct behavior !
But sometimes at random times the view switches back to showing all items. The tag that was selected is not grey anymore, but the "all items" goes grey !!
So basically loosing the items that were selected with a particular tag.
Also if a sub tag was selected, in the tag "tree", the tree collapses, only showing the top level tags.
Is there any way a log can be created for debugging this to help you Enpass people ?
