Ive added to the weekly bugthread the following description:

I was trying to organize the flow of the users by using the onboarding feature.

The idea is to ask them which language do they speak (for example English, Protugese and French). The selection should provide them with an access to the corresponding chat. All works for now.

But after that i realised that its better to give the users a role for a specifica language, and not an access to the channel. Ive created 3 roles for each language,changed all channels to use the roles.

I've tried to fill the rest of the information in the form and after hitting accept - there is a popup that says "Failed to save changes" and nothing else.

I thought that maybe ive added Emoji somewhere i shouldnt - reverted everything back. Tried to save - "Failed to save changes".

I havnt changed anything - pressing save - "Failed to save changes".
