Problem after update to 2.1.0.2 (Beta)

Pcloud and Duplicati is the forum topic linked by the pull request behind this 2.1.0.101 change:

Breaking change from previous canary

The pCloud backend is updated to support subfolders.
Paths with / will now be treated as a folder structure on pCloud.
Previous version would treat folder/subfolder as a single foldername,
this version treats it as folder / subfolder.

and since you found you were not actually on 2.1.0.102, this will impact your native API usage.
I would hope that you know how to move the files around in pCloud to satisfy both these cases.
