I purchased Join but I can't unlock it on android. Which means I can't send sms's from my PC. Makes the software useless until I can get this working. I believe I purchased Join from the PC. I have an email from Microsoft for the purchase. As far as I can tell I'm logged in with the same account as I am on the PC. Both devices are showing in the devices section. I've tried reinstalling it via the web version of the play store as suggested. It still says it is locked. I even tried going to the Microsoft page but they only seem to have the Windows version. I'm not sure what I'm doing wrong.
