I really like the concept, and the app works great.

After I listened to a podcast I withdrew all the sats to test it, and it worked fine.

But after that it never gave me any more sats. In the listening tab it keeps counting sats up to say, 5 or 6, and then it goes to zero. No more sats are ever added to my wallet.

What can be the cause of this? and is it possible to fix it?
