Fixed my @fdroidorg app on my tablet as I found it had a radically different idea of which versions of several apps were available than my phone had. Both were also behind reality, but that is normal. I noticed this because the @Tutanota app failed to download, maybe because such an old version (August) no longer existed. Somehow going into the 'nearby people' function triggered a new wifi permission popup, or maybe it was me toggling wifi off-and-on that fixed it. But after that thumbnails and screenshots loaded again and new(-ish) app versions were shown.
In researching this I found the remark that F-droid has supported unattended upgrades for a while. That is a feature I was really waiting for, as clicking Install on each separate update then wait a minute then click the next etc was getting really annoying. But it is not happening for me. Turns out that this is only available for newer Android versions, which neither of these devices has... See f-droid.org/2024/02/01/twif.ht… .
