Same happening for me too. In the UK :(. Please can this be looked into?

Hey, I pushed a potential fix for Europe today -- will release on TestFlight soon, but if you want to try it in the meantime you can build the app or run swift run bbcli --region EU from the BetterBlueKit repo and see how login goes.

I’ll keep an eye on TestFlight for the update thanks as i have the same issues

[Endwinad]

@schmidtwmark legend. Thank you for your fast response. I’ll wait for the new update to be pushed out via test flight. Thanks again for building a better app

Same for Canada, even with the latest update.

[alexiliesi-glitch]

Same for Europe unfortunately after the last update from today.

This should be fixed in 2026.9.0, released today

[screen-power]

I still have the same problem unfortunately.

[schmidtwmark]

@screen-power I'd need to see more information before I can help.

1. Turn on debug mode in settings
2. Retry logging in
3. Open the HTTP logs page in settings
4. Share the failing log(s). There are probably multiple steps part of a single login flow.

It's also good to know what brand/region/vehicle you have.

I see this in the error response:

"The login information you entered is incorrect. Multiple incorrect login attempts may result in account lock-out"

Looks like your email/password is incorrect, can you double check it?

[screen-power]

I did, I signed out and back in on the bluelink app and even bluelocke with scriptable works correctly with my login info.
