Apparently, the update was only live for a few hours. I updated my TA-1043 from play store. The update was about 250MB. Couples hours later, I could not find the app on play store. Not even in my last updated list. So, I logged in to the play store on my laptop and there it shows that I do not have any compatible device. Here is the link to the app - https://play.google.com/store/apps/details?id=com.hmdglobal.camera2
Mine is fixed too. Camera app is 8.0260.80 (no update); got the August security update and that fixed it. I wonder if not all versions of 6.1 are getting the security updates - I'm not getting any notification for a camera app update at all but it's working already for me.
