Frustration with Loupedeck 5.9.1 and Razer Key Light Integration

Hello,

I’m really frustrated with the current situation. I specifically need to use version 5.9.1 of Loupedeck because it’s the only one that still supports the Razer plugins (including Key Light Chroma). However, I can’t properly log in anymore since the old client doesn’t allow Google login or even email login due to outdated authentication.

This leaves me stuck:

  • If I update to the latest version (6.x), the Razer plugins don’t work at all.

  • If I stay on 5.9.1, I can’t even sign in, which makes the version unusable.

I feel like I’ve lost access to functionality that I originally bought the hardware for, and it’s really disappointing that there’s no official solution. Is there any plan to restore compatibility, or at least provide a way to use 5.9.1 in offline mode so we can keep controlling Razer devices as intended?

Thank you for your time, but I hope this issue is taken seriously — it’s frustrating not to have a working path forward.
