This would be quite nice. I stopped using my HSBC account ages ago but still have it open. Quite a few years ago I suspended my AA Membership then simply put it out mind. Apparently that suspension ended recently and I was billed the annual membership fee. It wasn’t until HSBC sent me a text warning that I needed to bring the account back out of overdraft otherwise I’d be charged that I realised something was up.
A notification would be a nice addition whenever the team get around to revamping connected accounts.
