Hi Dominique
If I create a task in Google calendar (through my browser), with a due date of 1st of next month, and make it recurring (on the 1st of every month), it shows up in Google calendar as expected (the task is shown on the 1st of every month).
After syncing, the first iteration of the task (i.e., on the 1st of next month) shows up as expected in CG. However, it is NOT shown on the 1st of subsequent months. Initially, I thought it was a display issue, so I ensured that I had "Settings/Tasks/Display recurring tasks on all future due dates" checked - but that made no difference. So I opened the first iteration of the task (shown on the first of next month); the "recurring task" box is not checked.
Can you help? Thanks.
