Hi Adam,
Thanks for your detailed feedback! I'll try what you've suggested tomorrow, and send you back a bug report. I still cannot figure out how to send a message to you - see the attached screenshot when I click on your username.
While it sounds not practical, factory reset did solve my issue, like at least three times in the past (see this that I posted). I think it might be related with this post, but I haven't got a chance to test it with the latest sdks. Will do this soon.
Thanks!
