It is possible (but not certain) that this is a regression introduced by the newer electron version we use.
Unfortunately, the newer electron also has a bug with saving the performance profile so we can’t have a look on where exactly it gets stuck for you. We’ll see if we can update electron version in the next public release (No eta).
Mobile doesn’t use electron. The iOS/iCloud issue you linked is very specific to iOS/iCloud, we are sure of that.
