Incoming follows broken on latest develop
The remote Pleroma instance reports "Request sent", whether or not local users require approval. Locally there are no errors in the logs, nothing appears to happen. The block/unblock dance doesn't resolve it. There don't appear to be any errors in the other server's logs, either.
Appears to affect most other instances; no one on blob.cat or stereophonic.space or lets.bemoe.online at least can follow people on FSE. (Probably has something to do with the reworking of followers into a join table? Last thing that touched that code, anyway. I do not know.)
