Can't use Cursor tab when using my own API key

I’ve set up cursor in settings to use my custom OpenAI compatible endpoint and API key, but after a while of using cursor it says Cursor Pro is required to use Cursor Tab. My settings on Cursor website (correctly) shows that I’ve not used any requests of any of the models as it’s going through my custom API endpoint.

This seems to be an issue with the Cursor client I’d guess?
