I was running the app for the first time, went through the tutorial, chose "crypto key", the page to "import NFT" appeared but the place where the nft was supposed to appear was empty. I clicked the "import" button anyway but nothing happened and from there I was unable to go anyhere. Had to force-close the app, run it again, then it took me straight to the "NFT import" page and then the NFT appeared & was importable
