Hi Sophie & welcome 
The Barclaycard connection vanished around 13-Sep and hopefully will return 
Here’s why it vanished; https://truelayer.zendesk.com/hc/en-us/articles/360002158797
And here is where it currently sits; https://truelayer.zendesk.com/hc/en-us/articles/360004577454-What-banks-cards-are-you-integrating-next
I’m still waiting for the MBNA connection to go live. Truelayer supports it but it hasn’t been integrated into the Monzo app yet.
Any news on the amex integration?
Open the second link above. Tells you TL are hoping to add Amex
Hey everyone, sorry for the long gap in posts!
As you’ve all suspected, we’ve been waiting for the dust to settle on Open Banking and gently nudging TrueLayer about Amex, and I’m here to provide an update on all of that:
Amex
The headline here is that Amex still isn’t ready. Obviously this is hugely frustrating for us - it’s our most demanded provider both internally as well as externally and we’d love to support it. I’ll keep you updated but until they release an API and prove that it’s usable there’s very little we can do.
Barclaycard
We’ve heard that Barclaycard connections are getting more stable. That being said, this recent week saw problems specifically in the credit card API so we’re erring on the side of caution and keeping them under wraps for a while.
MBNA
We’ve been testing them internally and are seeing positive results. Keep your eyes peeled!
Halifax
TrueLayer tells us that Halifax have been working on their reliability a lot and should be more stable as of last week. Do let us know if that’s not the case for you!
Bad news aside, I’m happy to share that Nationwide and First Direct are now available for connection!
Give them a go and, as always, any feedback here is greatly appreciated. Thanks for holding out for this feature with us, we’re really excited to keep at it and make it fantastic!
Santander seems to have appeared since I last looked too. And it seems to work. 
What about Tandem when they come?
That’s down to TrueLayer to decide in the first instance, as are all the others.
Thanks for the heads up about Santander, I stopped checking but have been awaiting that one
My Nationwide credit card is connected and shows a balance but I can’t see any transactions- is that correct?
Yes. Balance is all that’s on offer at the moment.
Ah shame! Especially as Emma allows the transaction detail and I was hoping to delete it!
As with so many things, that functionality is hopefully in the future somewhere.
Hey Michael 
I’m having issues with my connected Halifax credit card. It’s been well over a month since it has updated itself. I’ve tried the usual disconnect then reconnect card (which gives it a 1 time balance refresh), and also deleting and reinstalling Monzo, but nothing has fixed it.
Any suggestions?
Monzo 3.8 (App Store not TestFlight)
iOS 13.2.2
iPhone X
Hello! If you ping us a message over in the Help section of the app then I’ll take a look
Thanks I’ll do that now
I’ve sent a message in the app now 
I’ve just reconnected my card (again). I had reconnected last week and it was disconnected again yesterday. Will see what happens.
Any updates on Tandem
