I can post on the Lemmy website (typing this on my desktop right now), and I have downloaded and installed a couple of the apps listed above on my Android phone, but I can’t log-in into any of them.
I have tried many times over a couple of days now so I don’t think it is because of the Reddit refugees swarming this site or those apps, but maybe I am wrong.
One rather confusing thing is that when I try to log into wefwef for instance (but I think the other apps have something similar), it asks for Account’s server. I don’t know. I pick lemmy.world but I am only assuming that is correct. Then the next screen asks for username or email. I’ve tried “Hazdaz”, I have also tried the email this account is tied to. I have tried all lowercase. I have double and triple checked my password. But everytime it says “double check your credentials”.
