This Joplin cloud...

I've been using Joplin + webdav together with pCloud. yesterday that stopped working on all machines, error 443. i have a current forum topic created for this.

but if this turns out to be unsolvable and i have to get joplin cloud basic (1GB), well I checked my folder size and it's currently 5.8gb. so what would happen if i switch over?

Found this in another post.
