They’re not trying to get people to switch their current account to Monzo (at the moment?), but to upgrade from the prepaid to the current account. This is a ~3 minute process and adds FSCS backing to the person’s money.
Even with CASS, asking someone to switch their current account is probably going to be a much harder sell than asking them to convert their prepaid card to an upgraded version of the ‘same’ thing.
Can’t wait for golden tickets. Does new sign up with a .ac.uk address get bumped up in the queue?
I got the OH to upgrade earlier!
What are the minimum app / OS requirements to upgrade?

You’re upgrading the account, not the app! Having said that, as previously announced, they are dropping support for iOS 9 at this point so that may be a limiting factor for some.
As long as the prepaid app functions, you can still use that app Just update it through the App/Play Store Android 5 or iOS 9 are the minimum requirements
Same thing happened to me: I received an email to upgrade yet I already have a CA. Never owned a prepaid card.
Yes, it appears there was a tiny glitch for the small handful of us the Monzo fairies blessed with a nice glittery current account who never wanted a prepaid card. @anon76573274 couldn’t possibly have known and Monzo’s amazing 
I can’t see any pots, app in store is 1.16.something.help? Thanks!
Interestingly, my wife was running a very old version of the app. It wasn’t until she manually upgraded it that she got the banner
Thanks Will, however I’m not sure how to upgrade manually! I think I’m missing something simple… hopefully.
Go into your app store and see if there’s a new version
Nope, it’s 1.16.1 in app store. I’ll just wait. Thanks Will.
Hi I heard If I upgrade to the Monzo Debit - I have would have to give up my normal current account as in do a switch to be upgraded on Monzo. Is this true?
Where did you hear that? It’s completely, totally, 100% false.
Hi, no there’s nothing stopping you keeping your other account open, lots of people have multiple current accounts (I have 3) ️
No. Monzo is not currently part of CASS (Current Account Switching Service), so you can not ‘switch’ even if you wanted.
You can, however, upgrade your prepaid card to a current account and try it out to compare to your, erm, current current account.
I’m pretty sure the term and concept of switching long pre-dates CASS 
I’m unsure if you’re trolling, but, in the context of current accounts, the term used is generally understood in the context of CASS, which is why I provided clarification.
