Review for Provider for Google Calendar by Martin Shaffer Levac
Rated 2 out of 5 stars
TB 24, provider 0.25 with Lightning 2.6: TBird always freezes unless I deactivate Provider for Google Agenda.
With previous versions of Provider and TB and for years, always had major system slow down while Provider was syncing, even making other apps fail, no matter if it was on WIndows or Ubuntu Linux (yes I carry a big bunch of events with it, but a reliable add-ons shouldn't worry about it).
May be good stuff for amateur with almost nothing in terms of data volumes but absolutely a bunch of trouble for serious production environment.
Until a version 1.x is released am looking for a reliable way to sync Lightning with Google.
