I’ve noticed this for a while now, whenever I try to edit a long-ish post, while I have Apple’s Private Relay switched on I just endlessly get the ‘saving’ animation.
Also keeping getting this: Spurious "Draft is being edited in other window" errors (with or without the APR enabled) Might be related.
I think it might have something to do with the size of the post, but don’t quote me on that. Or, it could be a problem with the device you’re editing on/Private Relay.
It’s intermitted, some times it works other times it doesn’t (but has happened often enough to warrant reporting it).
The “Draft is being edited in another window” has been going on for quite a while, tho I think @Sam said they were going to look into it.
