However I was not really able to monetize in any form (needs permission from Spotify, and Stripe shut down the account before it got to even do anything). Did you encounter similar issues and if so how did you circumvent them?
I'm at a loss now and on the verge of shutting it down, but I have a few hundred users that periodically email me to ask for fixes / new features, and it pains my heart to just give it up like that, but it's just not making any sense economically for me now.
