re: iOS 10 Dev Beta 2 is Live
With the exception of the odd layout of the icon grid, the spacing is not right horizontally, every single app that I've opened and used (and tested key functions) is working just fine, without one application crash (mind you it has only been 30 minutes).
Hope the following list of tested apps helps someone, I haven't found ANY issues at all, and have included the functionality that I quickly tested (iPad Pro 9.7" with iOS 10 Beta 1):
Overcast (playback & download), Facebook (tested photo upload and post), Slack (tested two teams with one post), 1Password (tested touchID auth and opened a few items), Plex (tested video playback whilst streaming, full screen and PIP), Feedly (sync & open a few articles), Google Photos (open photos), Foxtel Go (watch streaming video in window and full screen), Fantastical (open and create new appnt), iMore App, Workflow (tested gallery download and launching workflow, might be an issue with map look-up), Excel (open existing spreadsheet and create new one), Word (open and create doc), Zinio (open and download mag), Facebook Messenger (open and send messages), Calendars (by Readdle), Spark (send and receive email), Notability (create and open notes), OneNote (open and create notes), Airmail (send and receive email), AVPlayerHD (open video & test PIP).
