I can add to it that half a year or so with older version of Xamarin.Forms etc it was working, due to another problem I had to update my android app (Android 12 issue), and now all of a sudden encoding of QR codes failed to work. Very inconvenient of course because now I can not fix the other issue because of this problem. If I can assist somewhere let me know. — Reply to this email directly, view it on GitHub<#472 (comment)>, or unsubscribe<https://github.com/notifications/unsubscribe-auth/AA2QMUQEQMUJM7L73ZZLUD3WONMUNANCNFSM6AAAAAATF52JYY>.
