This post will be updated with a summary of the feedback reported with this firmware. I’ll be collecting all of the feedback and sharing it with internal teams as appropriate; I’ll do my best to respond to you in this thread but might not be able to reply to every single post. I may also include other issues identified through our own internal testing.
Thanks for your help!
