I've edtied your post to remove the multiplayer code, please keep in mind that other people can join the submission when you share it. Github keeps a history of your edits

I've tried a lot and published a few new versions and I cannot figure out why this is happening or reproduce it outside of production.

My current knowledge on this issue:

• category gets from database (works fine, added an index for fast but did not matter)
• Slowdown and no response. I have no clue where this is happening.

Edit: I have no clue what is causing this

Update: The application code is not the problem, using a share code (somehow) works fine on sandbox

I have added extra logging to the backend and saw that at least 1 person came through the entire flow. I think the backend is just overloaded currently and not able to process the sheer amount of requests it is getting. Looking into solutions
