I get the 'You are already logged in with a different account' whenever I try and complete the most simple action, it's infuriating.

I've got a few flights coming up, so wanted to check seat allocation and get the flights numbers. After completing one thing and moving onto the next, I get the error. Locking me out of my account for ages. If I click the 'log out' button nothing happens.

I'm logged into BA app/website on a few devices (iPhone, iPad, a personal and a work laptop- but nothing unusual in that) and should be able to access the same experience across multiple devices

BAs tech is beyond a joke. How long do we have to wait for a semi-functioning website. It's 2025 for God's sake. Each update make the website more buggy and poorer functionality.
