lots of problems with new features updated

[supreeya2030]

the first problem is a difficulty of using a keyboard on iPad. Every time I want to type, the line for typing disappears in a second and then I have to tap many times and when I type, it suddenly disappears.

next one I can remove the participants as I could with the previous version.

I have to tap on the screen to see the tool bar, that is also annoying.

And then when I want to see the participants, the screen is covered with the big box. 

Finally, today I have a problem with using a pen to write on the screen while sharing a document.

Please fix it as soon as possible!!!!!!!!!!
