Seems that the duplication of calendar items is no longer an issue for me after upgrading to 126.96.36.199. But now I receive an error (see image) after syncing with Gmail Calendar. Will send the logs to PB's super support team (sst) but is anyone else experiencing this? By the way, the syncing occurs correctly, the items are added from PB to GC. Restarting does not clear the error. The error only appears upon selecting to sync, not upon starting PB.
Update: worked a bit, created some calendar items. Selected sync expecting the error, which did not happen. What did happen is a duplication of calendar items in GC. We are back to square 1. Sent logs to sst.
