I had been running Poweramp v2. When it automatically updated to v3, it broke the song info display via bluetooth connection to my Toyota Sound System. I had to download and install the v2 apk (Poweramp-2.0.10-build-588-uni.apk Build 588) to restore the song info display. Now I am getting a message that the trial version has expired and I need to verify purchase. When I input the Google purchase receipt it takes me to download page for v3. According to PlayStore purchase history, I purchased Poweramp Full Version Unlocker January 18, 2016 for $3.99. How can I verify purchase but not install v3? Thanks.
