@nseslija Not necessarily before each activity. I had three four activities since i powered off and on, and all of them worked. I had a XC skiing between those and a bunch of indoor activities, as well. We’ll see how many I have to do before the the app croaks up. Recently, i check mid-day and after completing an activity to see if the app works, as i plan to send the logs, if it doesn’t. But so far, so good.
