Hello,
since a few weeks now on some tizen models (noticed on 2021 models) uninstalling the app stopped working. It works fine on older model years with the same command. I'm using sdb -s ${ip} uninstall "${applicationId}" to uninstall it. The command executes sucessfully witout any output and after that the app is still listed as installed. Installing/starting/stopping the app works without problems. It is still possible though to uninstall the app manually on the TV.
SDB version: 4.2.16
