Take 21 sats for your troubles friend.
Did you reach out to them? I know a lot of people that use it and works no problem.
Discussion
yes i did and they say that i veto resintall the app, clear cache and etc...but the issue remains
then a user told me, i may need to boost audio in order to earn
a bit strange way to do, pay to get pay later (if i was sur about it, i would have done it but for the moment i put it on stand by)
