"It appears you don't have a license of minecraft"

I uninstalled and re-installed the app to get off the Beta Testers list. Ever since then, this message shows up "it appears you don't have a license for minecraft". I tried everything to get this to work (cleared everything I could think of, restarted my phone, downloaded an external launcher, etc). NOTHING IS WORKING. And yes there is already a similar complaint here but since it has not been resolved I hope this garners enough attention so as to get it fixed. Please do something. I don't even want a refund I just want it to work again...
