Wix Issues : My bad experience with Wix

I heard that Wix is user-friendly and easy to build websites. I'm tech-savvy so I was confident when I took the job. However, I'm at my wit's end with Wix.
Here's why :

1. It's slow!!! I have to save and refresh my page just so I can resize the section.
2. Editing on mobile is a mess. I added a color background on a text and everything is upside down on mobile. so I'm going to spend another 1-2 hours redoing it
3. It's constricted. I can't do what I want in terms of design. It's like wix is laughing and telling me "this is all you have to work with. have fun (evil laughs)"

can anyone recommend a YouTuber that can explain how to make wix easier? maybe I missed something.

Stay away from Wix, i cant say this enough! I dont know how many clients i have had that built their sites on Wix and i had to rebuild them in Wordpress. Rather build a Wordpress site, easy to learn and can do so much more!
