Yes. This does happen.
Let me put it in pictures, during many minutes.
There's a guy up top, without bountyamount.
And the bounty never gets there on that player.
so not a first hand issue after table change.

Little update to this when noticed something. 

The jam is most likely to happen when you press the screen and drag the finger over the MTT lobby filters at the top. Tried several times, and always repeatable. Not sure if the drag needs to end up on the filterbutton or in between them, but that's how you do it. Might take few attempts, but not too many. 

Turned on the touch indicator from developer settings on Samsung galaxy tablet A7. Vids added.

Most of the glitches happens when tables are changed, or break is about to happen.
It's infinite.
See same Chat glitches come back from somebody else.
At top left corner, emotions/animations are had. Problem is, that the cursor of mine was playing elsewhere at the same time.
So Whos reactions are those, Relax?
Fun, aye?

Happens more than sometimes. I play from livingroom sofa maybe more than half of the games in general, and the routine to get away from that freeze has become an artform to muscle memory and instincts.
Steps to get away from it are as described by OP. Best way being to kill all running apps the moment, and enjoy the fact the app logs you back in without passwords ASAP.

Exact steps to reproduce are still unkown for me, but it helps to casually tap on to the MTT lobby games as usual in the middle of screen in order to move it, and thefore when dragging the list up or down, hold one of the games under finger microseconds longer the app can fetch info and keep up.
It's like being given double commands, and doesn't know what to do, so softlock or whatever, idk.
Everyday stuff anyways.

Androids 7, 11, 11, 12.
All but the 7 are Samsung galaxy models, 7 is Huawei Mediapad

Call it an issue or not, but true issue is the mobile MTT lobby freezing continuously (Samsung), to which the killing of all apps is a fast cure.
The idle time that remains despite logging out or just killing apps is a bliss, in order to log back in quickly, IMO.
Like said above, good to use phones/tablets screenlocking password for it, if the issue becomes realistically troublesome.
It is a thing that happens, tho. Everytime.

Yeah. Basic sight in the end of every tournament. Or in the middle of them.
