Update on 2 Nov 21 made incoming audio inaudible. Tried voice and vid call both ways. Same problem. Tried on Win 10 with webview both ways. Same problem. But my outgoing Vid and Audio good at other end using both versions. First time updates have made Duo unusable. Next - Tried FT both ends. No problem. All was with USA UK contact. Next day tried UK UK. Same problem. EDIT: 2/2/22. Used again - just as bad. Advice by Google to delete / reinstall on Galaxy 10+... Impossible. Its a permanent app.
