My instance discuss.online recently switched to a new version of Lemmy that causes Connect, Liftoff and Jerboa to either crash or being unable to log in. It has a sticky with admin’s comments to check and reach out for more info. When these updates will be rolled onto other bigger instances, it may render clients unusable until a quick fix on their side. Be aware.

edit: That sticky is there https://discuss.online/post/1294119
