Categories such as “education” are useful for limiting access for specific groups of devices. For example, if one class has a particularly mischievous group who keep going off task from their devices, rules can be created to whitelist certain categories, and only pass traffic that are in these more straightforward categories. Just FYI.
It’s a shame. I did pay for lifetime, and that’s always a risk. Looks like this bet didn’t pay off. The money doesn’t bother me - more the fact that there isn’t a portrait-only Lemmy app that’s a good replacement. If anyone knows of one that’s as good and will stay in portrait without having to put the whole phone in portrait lock, please let me know…
