Maybe? I'm not sure what "application" you mean. I'm posting here, so my account request on lemmy.world was accepted. Not sure what other applications I would need.
Do you have a long password? I had the same issue with a 64 character password. Apparently the web interface implicitly truncates long passwords to 60 characters, but Jerboa doesn't (Jerboa issue #425). Once I changed mine to a shorter password, it worked fine.
Yep, 66 characters. Tried changing it to a (much) shorter one, but still having the same issue. Reading in other communities, it seems that lots of people have problems with Jerbora, and lots of other people don't. (sigh).
Update: Seems that the password change didn't take. But deleting the last 6 characters of the password when logging into Jerbora seems to have worked.
Seems like there might be a similar issue with the old password length in Lemmy when changing the password. Ugh.
I'm also on lemmy.world and jerboa is working ok for me. Two jankinesses I'm aware of are:
In certain scenarios where the network gets interrupted, Jerboa seems to get permanently confused and is unable to recover. The workaround is to restart your phone or go into app settings and force-kill jerboa and it will work for a while again. This happened to me a bunch in the first few days (maybe in response to server restarts) and has been ok since. I saw this AFTER logging in and it would kill my session. Not sure if this would affect initial login or not.
I've read but not experienced that Jerboa gets confused by passwords with commas in them. Do you have one of those in your email or password? If so, maybe try logging in via username or change your password to something different.
Yeah I've noticed all sorts of odd issues with Jerboa. I think the best solution for now is to keep using a browser. I heard that someone was working on a reddit compatible API for Lemmy so that apps like RIF can have an easy transition. I think that might be the best end solution tbh, to use apps that are already well built.
