reinstall wouldn’t help: Updating apps seems broken - #15 by Art
Besides the OnePlus 6 I use a Samsung 9 with /e/ which is experiencing the same issue.
I prefer f-droid (+ some non-free apps with Aurora store) over /e/ App Lounge - please note: you have to de-install/re-install any apps if switching to/from f-droid store as f-droid builds/signs apk with their own keys.
