Yes your points make sense re: which system is broken and it appears we have logs to suggest which one it is. The end result however is that users can’t use pcloud to sync with Joplin.
What about speed? Aside from the inability of pCloud’s webdav server to sync properly with Joplin. Is WebDAV a generally a slower protocol than a direct token type of authentication?
I did some some speed tests and to sync my data set with Dropbox it takes around 3 hours. With the pcloud webdav server it takes around 5. I tested several times on different platforms. Even after the sync is finished, if I manually click on the Syncronize button, dropbox reports back in 3 seconds- Complete. In pCloud it takes 2m50s just to return a “Complete” message.
So I thought that Dropbox must be a faster service than pcloud but I don’t think this is the necessarily the case either. I have seen review articles which showed them to be similar or even that pcloud is faster because dropbox aggressively throttles uploads. If I compare syncing with rclone to dropbox and to pcloud the time to sync a data set it similar.
So the difference is the webdav server. I am not sure if webdav is slower than token based authentication in general or if pcloud’s webdav server in particular is slower.
So speed could be another reason to support token based authentication.
