Rated 4 out of 5 stars

(see my two previous comments)

Now I think I know what happened.

The day I switched to version 1.0.x (some day in November '14), the add-on suddenly turned ALL PRESENT AND FUTURE EVENTS to status "Tentative", leaving PAST EVENTS untouched.

But once this has been carried out, new events could be created normally, with the correct "Confirmed" status.

The only cure was lengthy manual reset...

I hope it won't happen again!

This review is for a previous version of the add-on (1.0.3).  This user has 2 previous reviews of this add-on.
