Hi all with beta trouble: I went through same issues myself, but in the end I got the beta to my Android:
1) register in thsi G+
2) wait to get admission to the beta program (!!)
3) then go to Google Play - but what you see looks foolish - it is old version from April 8th, HOWEVER
4) once I got it installed, it was in fact the desired beta version,
5) the information pane shows v 2.20.2.2, but News only shows old, original April 8th version info
6) no ads, with Pro functionality until May 30th
Hopefully you can reproduce above.
Good luck
Michael
