Google likely installing its malicious code to corrupt your minds .... despite their corporate policy of being un-evil, they are indeed veeeeeery eeeeevilPhew! Thanks for your patience!
Now the sad news is there was no problem. I just resubmitted a new build with the exact same code as the previous version. It seems like maybe there was some corruption on some content mirrors on google play store’s end. I had heard of someone else having a similar experience with their app and just rebuilding and resubmitting a new version fixed it for them so figured it was worth a try.
How frustrating for all. Thanks again for your participation here and patience!
Quite possible they fixed something maybe on one CDN data center or something which could explain this now working for you but not others earlier.And, by the way an uninstall and reinstall worked...
