in short : i followed the steps. BUT that deprecation message only is shown when you click uninstall on the app, than the message is shown in the same menu where i just uninstalled the app - it was not shown when still running the deprected app. i can then install the deprecated version again from the same tab, the message points out "breaking change ... still use this version ...." but it will not show the deprecation message if you just use the app. you would then have to head over to the appstore, where you only find the new version.
