Cannot delete photos and other picture issues

I don't know if this is a browser thing (Windows 10 Edge) but I cannot delete pictures from my models. I click X, nothing happens.
I also cannot click on the text. I have to right click the text box to put the cursor in there to type, strangely enough.

Also, I know there was a recent policy change, but I would like to be able to set a picture of my choosing as the default image, not a render. If I have a painted example of the finished product, I would like to show that instead.

Finally, on my phone only the default image is available. I cannot view the additional images at all.

Maybe, other browser (Win10 is too new)?

I was able to delete pictures in internet explorer. But that doesn't change the issues with not seeing photos on the cell phone.
Just FYI.

It's known problem, use other browser.
