Beware!
This unsubscribed me from twenty+ communities on all of my instances. It first tried to subscribe all of my accounts to all of the communities of my largest instance, which is what I wanted it to do. One instance failed to sub to 20+ communities, which was fine, as it was a smaller instance.
Ten minutes later, however, I got a notification that it had unsubscribed all of my other instances from those communities as well. It took me about an hour to figure out most of the ones that had been lost, and even now I think I’m missing a few.
Here is everything I can remember doing:
Downloaded the apk
Installed and opened the program
Allowed notifications
Input my four instances: lemm.ee, sh.itjust.works, lemmy.basedcount.com, and lemmy.ml
Hit “sync” and watched them sync. Three of these instances had almost the same number of communities (around 120), but one had none whatsoever. It took two or three minutes for that instance (basedcount) to sync all of the communities, and in the end, it wasn’t able to subscribe to about 20 of them for some reason. (maybe because nobody had ever gone to/searched for those communities from that instance before - I’ve heard this can lead to access problems, but you’d probably know more about that than I would)
About five minutes later, I got couple of notifications saying that 6(-ish) communities had been synced and that 18(-ish) had been unsubscribed across my instances. This confused me, so I checked my instance list and saw that all three of my instances with around 120 communities now had around 95.
I disabled notifications because they were starting to feel spammy.
I looked at the notification again and realized what had actually happened. I immediately uninstalled the program and resubscribed to as many communities as I could on lemm.ee, my main account.
Sorry this is so long - I hope it helps!
