Whenever I try to use custom assistant, it tells me to set it up(To use custom mode, you must set it up in the custom assistant settings page.) when it is already set up
Custom prompt censored for privacy reasons. Changing it did not solve the problem
Preferred assistant mode also does not work when it's set to custom assistant and fallbacks to Research mode.
I've tested this on Librewolf and Brave Browser on Windows 11, Fennec on Android. This does not seem like a client-side issue, at least that's what I think.
Desired Functionality: Working custom assistant mode.
