[Developer Mode] Login user ID - invalid format

I enter the account I logged in to the LG developer site as it is, but I can’t log in.
This account was in use until the webos 24 update.

Please try reinstalling the developer mode app. If the problem persists, share the following information:

  • TV model name: (You can check this in the Settings > General > About This TV.)
  • TV software version:
  • webOS TV version: (This can be found when you click the TV model name in the About This TV menu.)
  • Region:
  • Developer Mode app version:

I have the same issue. It worked untill update. Any solution?

We apologize for any inconvenience this may have caused. The issue has been fixed in the latest version of the Developer Mode app. Please try reinstalling the developer mode app. Thank you.
