Recently I've been trying to create online game play using the global cloud Variables that are supposed to update when other scratch users are running the project, but for some reason when I use the variables they don't update like their supposed to. Is this a problem anyone else is having?

yes. the cloud variables are turned off. it's been like A YEAR since this happened, and it might take a few months.

As @-Thivo- helpfully stated, cloud variables are currently broken. All we can do is wait for them to be fixed.
Unfortunately, no one knows when they will be fixed, how to fix them, or why they're broken.
This affects every Scratcher, so the Scratch Team is aware of the situation. They are working on a fix.

Thank you for informing me, I had no idea this happened and I thought it was my computer or something.

Please fix cloud servers, I’ve BEEN WAITING FOR 1 MONTH AND 2 WEEKS!!!

I am facing the same problem as well. The ST is aware of it and the engineers team and the backend team are working hard to fix this issue.

You can just share the project, but tell people that it doesn't work on Scratch and tell them to use Turbowarp instead, because their cloud variables still work.
