Question UI not working for 16:9 but working for 18:9? 2022.3.4f1

I m making a mobile game and i was working on 16:9 aspect ratio. On the scene tab it looks fine as it was but on the game tab UI Text and Buttons disappeared. If i change the aspect too 18:9 it looks fine, the buttons
reappear and it looks okey. Why? It worked fine for 16:9 before and i never used the 18:9.

 

With free aspect ratio you can see how the buttons move when the ratio and resolution is changed.
Probably a bad canvas setup with the anchors

 

Is there anyway too fix it? I just can t find the solution? I don t get it how in 18:9 works and on 16:9 everything dissaper

 

Yes, but apparently you didn't read it above. I'll repost it for you:

Go fix it.

Here are some notes on UI Anchoring, Scaling, CanvasScaler, etc:

Usually you need to choose a suitable ScaleMode and MatchMode in the Canvas Scaler and stick with it 100%. Generally if you change those settings you will often need to redo your UI entirely.

I also use this

CanvasScalerOrientationDriver

utility to make sharing UI for Landscape / Portrait easier. Read what it does carefully.
