Without using any plugins at all one simple thing you can do is not change the Offset of the UI but the scale. Leave the offset at 0.
That’s what a friend once told me as I struggled with the same thing and I never believed him but then I got tired of trying all these plugins and none of them worked for me.
So I tried it and ever since my UI has been scaled properly with no hassle.
Let me know if you need more help in understanding how to do this! I would be happy to record a video or send screenshots!
He explains what I am trying to say much simpler and better!
Hello everyone. Sorry for the late response as I was busy today. I used the recommended plugin(s) and they worked! I used the mobile device feature and they seemed to fit so I think they did. Thank you everyone for the help I actually do appreciate it!
