IPad Pro: Citrix Receiver 7.0.1 does not address any issue, not even error 51?

There is a new Citrix Receiver for iOS version, but it does not fix a single issue of mine. 

Not even the Error 51 it says it should. Also it mentions X1 SHIFT-CLICK or CTRL-CLICK but I don't know where they fixed it, as it does not work for me in the windows explorer or any other area that I need this.

I'm waiting desperately that Citrix Receiver will actually fix the following:

- rubber band selection (SHIFT+CLICK, SHIFT+CURSOR UP/DOWN), selective selection (CTRL+CLICK)

- native resolution support of the iPad Pro, currently only 1600x1200 with manually selecting the resolution, auto selection is much lower.

- multi key presses !!! 

Interested in:

Pen support, i.e. with the mouse you sometimes can kind of draw in onenote or other applications, not sure how and when it works. Most often press mouse button and draw. Now since there is an Apple Pencil Citrix receiver should support it only for mouse, click and drawing options but not to move the citrix receiver session around.

Nuisances:

- copy/paste absolutely drives one mad, workaround of disabling the clipboard on the TS helps.

- Error 51

- Keyboard sometimes lost, workaround: switch between iOS apps can help but not always.

- X1 mouse cursor lost, workaround: switch between iOS apps, usually helps

- Keyboard layout changes, strange behavior but I usually get it to work, workaround: switch on the remote session to 2nd language
