no calendar synchronisation since nougat update (htc m9)

[Dreamed]

Since I updated to nougat, my calendar app (Business Calendar) does no more synchronize with google calendar.
How to get it work again?

Welcome to Android Central! Moved from the Nougat forum to the M9 forum, since it's more likely to be a device or app specific issue.

First, go to Settings>Apps, select Business Calendar, and Clear Cache. If that doesn't help, then try wiping the system cache partition: https://support.t-mobile.com/docs/DOC-31522

If that doesn't help, then it's possible the app has some conflict with HTC's Nougat update. Send an email to the dev and let them know about it. support@businesscalendar.de
