Hi @Elmar, same problem here not possible to install on Homey 2019, Software Version 13.1.2.
When I go to the app store and select my Homey to install, it says the app will be installed shortly, but nothing happens on my Homey. The app doesn’t install.
The other email app from Adam Noren don’t work anymore on Homey 2019, I use this longtime but don’t work anymore.
