I used these instructions to update: [HOWTO] Update /e/
I wasn’t one of the lucky ones and had to use a manual update (section B). I could not do the OTA. I downloaded the image to the phone and did the update through TWRP which appears to have broken my syncing of calendar and email. So…
Last night I did not have any luck connecting the calendar app on the phone to the /e/ servers. I tried to create an account in Settings -> Accounts with no luck. (I didn’t try too hard )
This morning I downloaded a fresh image from the net and flashed it via adb sideload and as is expected I had to setup my /e/ account on the first run. The calendar and email now sync.
