Same here, and unfortunately OTA is not working:

It's also a huge step up from my feature phone. :)
At first I wasn't sure if I was leaving behind my Android phone, but I'm going to do it and trust things will improve although right know my smartphone is not as smart as it used to be.
For me the biggest issue is the email app not supporting self-signed certificates. I've been self-hosting my mail for the last 10+ years and this is the first time I regret it ;)
EDIT: ate a word
Oh, well... now I have mail back in my phone. I guess the "0.1alpha" in the User-Agent is well deserved ;)
I noticed that on my phone, it has actually vanished from notifications at the moment and yet it's been there all day, so maybe something is already underway.
