Other NFC apps are automatically started when the card is touched. That stops the running Satodime app and breaks the process. As other NFC apps (e.g. Google Pay) do not have the same problem, I guess the Satodime app is missing something that maybe declares it as an NFC app and stops other apps to handle the card when it is detected?
To replicate, just install the Mifare Classic Tool (https://play.google.com/store/apps/details?id=de.syss.MifareClassicTool&hl=de_CH&pli=1).
