As of todays update, the keyboard and scrolling issues should be fixed.
As a beta tester, I'm not really sure what I'm allowed to say about upcoming changes in the client.. so I haven't posted here a lot. But let me take a moment and help squelch a few concerns:
Waze appears to be taking appradio support pretty seriously. I just joined the iOS beta team, and within days of my posting about the keyboard issues, or the scrolling issues.. it was fixed and available in the betas.
They don't seem to say too much here, and.. as I said.. I'm not sure how much I'm allowed to say.. but please know they are working on it. And they do take our feedback seriously.
If you guys find any "appradio" issues in this new version (3.6) please let me know so I I can get it tested for myself, and get a proper bug report written for the Waze team.
