purchase – Boom: Bass Booster & Equalizer Review

i purchased this in 2017 using all features. i contact the app developer they restored my purchase. just updated it this past week took away my features and now i can’t use it at all unless i pay for subscription. im abandoning almost past app purchase due to this forced subscription use. you own nothing at the end.
