Can't upgrade from 7 to 8 Personal - fill-in fields not fillable

I think I've solved the problem. I was trying to update from 1Password 7 to 8 without creating an account in 7 first, as described in the upgrade guide. I followed the guide and now I'm on 8 on all my devices and things seem fine. The only suggestion I would offer to make the process smoother is to have the "upgrade to 8" in the help menu in 7 go directly to this guide. That would have made life easier! Thanks!
