It sounds the same as thyis recent post:

Sharing using qr code to Android not working

Hope everyone is doing good? Has anyone had an issue when sharing a project using the qr code, project made in IOS but sharing to Android. The Android just wont see the code and load? I have managed to share other projects with him, but for some reason it wont pick this one up? His wifes Iphoone worked fine, just his android wouldnt work. I had a look on here but didnt find anything conclusive that we could be doing wrong ? Any suggestions? Many thanks

Pete.
