I have a MAC computer with Sync. Was set up under sync Beta. I have an Android phone synced to it that was synced using the pair this device function. It works perfectly. I just got a new Android Tablet and am trying to add it to my sync and it does not seem to have the pair my device function. It insists I log into my sync account. So I try it and it tells me invalid userid/password. I verify and it is the exact email address userid that shows as being my sync account on the MAC. I verify the password on the MAC and it tests out fine. Try the tablet again and invalid.. So I try to reset my password on the tablet and am told my email address/account name does not exist. I just verified it AND Synced my MAC using it!! I have my recovery Key but there is no place to input it into the tablet. There is no place on tablet to enter the link device codes. How can my account be valid and in use on two devices but invalid and nonexistant on the new one? And How do I get the New one to sync with other two?

Been a week and not a single sign of any help or support. Not what a good trend considering how long I have been using and recommending Firefox. Is this the support can look forward to in the future?
