That’s great advice for every OS upgrade, as certain app versions are gated by Android version, patches, etc.
Another good thing to check is the Google Play Security Updates in the Security area of settings.
I would hope that these would be part of the post-upgrade done by Android, but it seems not for the time being.
Radio 
app missing, chrome browser will not update, update using Zirconia OS, everything is good 
I can confirm the missing FM Radio App.
Does the Play Store give an error for when Chrome fails to update? I can’t reproduce that.
For those using Zirconia units (don’t know if Emerald devices are also affected), is the battery drainage problem now resolved?
Chrome did update, 
, still no radio 
Okay, I dumped the FM Radio app from my Teracube_One Android 10 ROM using APK Explorer.
I sideloaded it onto both my Zirconia and Emerald Android 12 units and it seems to run fine. I can’t test, however, since I don’t have any headphones at present 
It also seems to run fine under /e/OS v1.11, as well.
Use at your own risk, as it requires sideloading from outside of the Google Play Store:

Incidentally, this appears to be the exact same build of FM Radio (AOSP) that shipped in the TeraCube_One Android 12 alpha image, so, I believe this is the most current one (or at the least, the most current one I have access to).
Happy to see progress and Android 12 working in Te2.
I will update as soon as Vowifi (Wi-Fi calling) is fixed. (I need this in our office because mobile network is not working in my office.)
Just trying this out, so will update as new things come up but the upgrade from 11 went smoothly.
The only two things I’ve noted so far is that when left plugged in overnight, the battery shows 92% charged and that Google complains that my phone software doesn’t meet security requirements (see screenshot) - it should be noted that my device is not rooted.
Update: The build is showing as not certified. Google Pay will not work.
Regarding the battery - see if that fixes itself over few days.
I got the same security notification this morning on my Android 11.0.4 despite being able to tap and pay yesterday. It appears Google is doing some sort of chaos with Pay currently, and it’s likely not linked to this update.
Hello tried out the android 12 the only thing so far is it just popped up that Google pay will not work. Opened and closed Google wallet a couple of times and now Google wallet does not complain about software. Will have to try it tomorrow.
I have a Teracube 2e with iodé. I have installed your com.android.fmradio.apk via USB transfering. The device has no access to the internet. Installing works fine. Starting the App: “FM Radio keeps stopping”.
Ah, alright. Worth a shot at least!
Sorry it didn’t work for you.
Your app breaks the WiFi connection. With installed app no WiFi connection is possible. Deinstalled and all is good, but without FM Radio.
Interesting!
I did not have that behavior under /e/ or the Teracube Android ROM.
The battery drain issue seems to be better, but maybe too good… I’m no longer getting notifications (or at least they seem to be very sporadic) when my device is idle.
I’ve tried disabling the battery manager, but that didn’t help. Not sure if others have seen the same?
** Edit: this seems to be a day-to-day issue. Today I am getting all notifications, but battery life sucks. Is it too much to ask for both? 
Zirconia download works fine. Android 12 good- missing FM radio.
Thanks🙏
Ok am experiencing difficulty with messages? Please advise. Thanks again.
What issues are you having with what message app, and what have you tried to fix it?
