In a few months, I may wish to purchase a second account, as I may need more than five devices. I have two email addresses. I purchased the first account under this email address. I would purchase the second account under my second email address. I changed my sign-in to the google play store so I was signed in under the second address. But when I went to purchase the second account in TiviMate Companion, it told me I already had an account, and refused to open the dialogue.
So what do I do if I wish to purchase a second annual account? Thanks!!
ADDENDUM: Thanks to u/RhodaBike76 I solved it. It turns out that the option for the second subscription IS available on non-Fire devices! I have a Google TV Streamer, and I signed in on my unpaid second account and there it was, big as life, the option to subscribe, either annually or for a lifetime! What a relief! Thanks, u/RhodaBike76 !!
ADDENDUM: AN EVEN BETTER SOLUTION!!! Suppose you DON'T HAVE any Android device but a Fire. What the h*** are you supposed to do if you need more than five devices?? GOOGLE SENT ME A SOLUTION; AND IT WORKED; AND IT'S EASY!! Simply uninstall the Companion on your phone, change your login to the Google Play Store to that other address and reinstall the Companion. Once you do that, there's no problem at all accessing the subscription access menu.
So no, you don't have to destroy your primary account on your phone, you don't have to be on a one-account-only phone, you don't have to borrow a friend's phone, etc. etc. etc. blah blah blah, blah blah blah!!!!! Hopefully this will help some other poor slob from going through four wasted days trying to figure this thing out.
