When trying to upgrade to Premium (which I've had before) I get an error that says:
"You cannot purchase this product with your account. We're sorry, the product you are attempting to purchase is not compatible with your LastPass account. Please logout and use a different account, or contact support for help."
I've checked the community support site and made sure none of the reasons for getting this apply to me; I'm not currently on a Premium plan (mine expired several months ago), I'm not logged in on a Family plan, and there isn't an active subscription through Google Play. I've tried different browsers, devices, and VPN settings (on/off, location, etc.). I'm currently located in Spain, and ensured my account allows for logins from Spain IP addresses.
What do I do next? I can't even contact customer support without a Premium subscription.
