in mobile view problem with pop up screen

1-) The text in the pop-up does not fit. need to scroll. This makes it look bad.

2-) there is a problem while uploading something. If you watch the full video you will understand what I mean. I guess it scrolls the variations down a lot when loading products that are out of stock.

3-) sometimes when I click to select variation it also scrolls down the variations.

I tried a few css but I couldn’t figure it out.

I ask for your help.
