It looks like a lot of hoops to jump through to upgrade to subscription of version 7. I have 6 running on two Macs, and 5 IOS devices, one of which is not going to be upgraded beyond IOS 9. So, if I march through the exercise of trying out version 7, losing 1Password on my IOS 9 iPod touch, and then I find I don't like that, -- can I go back to using 6 easily, or all the file vaults altered and non-recoverable. I'm only considering this because the extension for Safari no longer works. What a royal degradation for those of us who like older software.
Is this too complicated a question for you?
