Why is Adobe Express so bad on an IPad?

Anyone else having these problem working on an IPad? It’s an IPad Air, less than a year old. 

Apart from the items I want to edit flying up or down, despite me moving them very slowly, and the zoom not working well, and the side menu taking more room than the space needed to work on.  These are all little glitches that I’ve gotten used to. But my main frustration is the edit/resize bar just won’t go away. Once it appears it stays there.  This means I cannot see the top of my work properly.  It’s just always there on top of whatever I’m working on.  
I asked support months ago and the response was to “tap anywhere else on the page and it will disappear!”  As if I’m a child.  No, it doesn’t, that’s why I’m contacting support.  In fact their whole attitude was as if I must be wrong.  I shouldn’t have to get used to these errors and it does make work longer than it should be. 
This time I’m not accepting it, I want to know why. Why won’t the box/bar go away?  It should only appear when I’ve selected something to edit/resize, right?  And yes, it SHOULD disappear when nothing is selected.

so frustrating.
