Good day,

After updating from 4.2.0.2-ose to 4.2.0.3-ose, I started having issues in synchronising my external calendar.

Please see below the debug info.

Any assistance will be much appreciated. Thanks.

Regards.

Paulo

Hi Paulo,

This is a very rare bug that only occurs on Android 8.0.0 devices.

https://www.davx5.com/faq/java-lang-nullpointerexception-java-util-gettimezone

The only thing we know is that it's related to system caches. You can uninstall DAVx⁵, then install it again and it should work again. Or alternatively you can update your Android version.

Does this help?

Hi,

Thanks for the prompt reply!

I will try what you suggest, uninstall e re-install, and will revert. Upgrading Android version is not an option now due to availability.

Regards,

Paulo
