Installing 1Password 8 for iOS

I 've been a happy 1Password user on iOS and Macs for years. Just decided to make the switch to 8 on iOS (already switched one of my Macs). Is there a technical reason why the upgrade is not a simple upgrade button on 7 to move to 8? Anyway, I found the download button, and install. That worked great! I click around in 1password8 on iOS and everything looks great!

Ok next surprise 1password7 is still there :) Hmm boot up the laptop, google search, and I find this outstanding thread ! awesome.
This gives me confidence that i should just delete 7. There will be some "growing pain" as I get 8 integrated , i.e. get the right permissions back on iOS, in browsers, ...

When I booted 1password 8 for the first time there are a number of "help" type messages that come up in the app. I didn't see one for "Hey 1password7 is still installed adn you can/should delete it at any time" . Is there such an article? Why isn't it the first thing i see when I launched 1password 8 for the first time?

Thanks for listening!
