I am a returning user, I bought a renshuu pro lifetime membership about a year ago. Recently I logged in and renshuu pro is not active? I can't find a resync button anywhere. Any help finding a resync button or anything like that would be appreciated. Thank you.
It appears that they have deleted their account. There is no way for lifetime pro to deactivate, so the most likely conclusion is that they accidentally logged in with a different email (it happens more than you think).
If anyone feels like this has happened to them, you can always use the ? button at the top to contact me directly, and I can help you figure out which account you should be using!
