Every time I exit the app and get back in, it appears to be the not modded version, like installed from the Play Store, no premium features at all. Anyone else having this problem?

Use older version and wait for the update

no long work, the skip still won't go after 6 songs.

As RishavG already said, there is a problem with this version. Go back to the previous (8.6.12), wait for a new one, or keep complaining about this one. Your choice. I will post this to all versions because searching and reading is hard labor.
If you complain even after this... You need help.
