Also running Cherry here - but for a long time now. It wasn’t a Fairphone update, at least in my case.
However, something else got me thinking: we’ve got problems in our working group since the beginning of March when using Thunderbird + Lightning + Provider for GoogleCalendar. Some repeating entries stopped repeating with the 2nd of March, but should not have done so. We got rid of the problem by turning the “other calendars” off and on in at least two instances. (To be honest, also had other problems before, but that’s a different story.)
Since March 6th, there is an updated Google Calendar app (linked by @ddewit, above). It may be possible that they changed their bloody API, again, so the calendar which came out-of-the-box on our doesn’t work properly any longer.
I got no update message for this calendar, ever. It says it’s version 4.2.2.-eng.hjy.1406797706. @keesj, could you probably check with the Android developers if it’s an issue and see if this can be fixed in FP OS 1.8.2? (Whenever that’s going to happen… :sigh: )
To be fair: it’s the first point of Googles bloody troubleshooting guide to advise us to use the current Google Calendar app.
