I did the latest (from 18/03) firmware update today (21/03) and ever since then it keeps flashing between a few different screens:

- black screen with the actual time

- homescreen with incorrect data (I have date, time, alarms, water and steps, none of which are today's correct data)

- homescreen with partly incorrect data (here the date, the alarm and the steps are correct, although not for the time shown)

I can still do the things I usually do, as long as it's not on the homescreen. I was able to put it in sleep mode successfully after a few tries which seems to stop the issue as long as it's inactive. (the flashing kept interupting the process)

A restart fixes nothing
