Yeah, I have this problem unfortunately. And as mentioned above, I just learned to switch to desktop mode on my phone when I need to edit a post, and switch back again if need be.
I've found the easiest way to do it, is when in phone mode, click the link at the bottom that says "full site". And to get back again, I click the drop down box that usually says "bluelight Aria v4.1.12-ADS" and select "bluelight mobile". That makes it pretty easy and fast to switch back and forth. Some browsers have their own feature to enable and disable desktop mode for websites, but I've found it unreliable. So I use those links to go back and forth.
It's a little frustrating, but I've mostly gotten used to it.
