Every single UI element within canvas groups will NOT render at all. Occurs on both mobile and desktop. Interestingly enough, interactions on buttons and other elements within canvas groups still seem to still work, they just don’t get rendered. (game link)
You can clearly tell what is using canvas groups and what isn’t.
Expected behavior
Canvas groups render as normal.
We are also experiencing this in 💂 Buckingham Palace - Roblox. Any canvas groups and their descendants are not rendering.
They are broken in studio in UI and plugins as well. Our plugins that use canvas groups are all not rendering.
Completely frustrated. I’m experiencing this exact issue right now.
Wow I love it when someone at Roblox completely breaks my game! Woo! This happens on a monthly basis at this point…
Experiencing it in my game Obby Trials - Roblox
Also experiencing the issue right now.
The CanvasGroup renders in the Global ZIndexBehavior only.
Experiencing it in my game [V4] Comedy World RP Fixed
Bumping, my game is completely inaccessible due to whatever recent change occurred. Roblox for the love of god, stop doing this.
Hello!
The engineering team has made adjustments, and this issue should be fixed! 
Let us know if you have any other concerns.
Fixed on my end, thank you for the quick turnaround!
Still isn’t fixed for me, it should show a level bar, but instead it’s showing this:
Still doesn’t seem to be fixed in some cases
This is still not fixed! Making a new CanvasGroup, and doing absolutely nothing to it, will still break. I put a TextLabel inside of it, and it disappeared. It’s not rendering a thing. It’s just a frame that hates it’s children. 
The only reason I am using CanvasGroups is because they do fix the bar slider not filling in everything.
This isn’t the first time this happened:
Hey everyone,
Please ensure you have completely restarted your Roblox app in order for this fix to be in effect.
Let me know if they are any other concerns.
Just restarted Roblox and it seems to be working normally.
That was a pretty quick fix ngl
CanvasGroups are not yet fixed for me.
This is in-game on new servers
some of my players are still reporting this bug today
