Please contact support again, provide system diag after installing the app - as I mentioned, no developer can influence anyhow the way Homey app store installs the app - I can specify the compatibility prior to the installation, but you do have compatible firmware version. THEN - when the app is initialized, then developer is responsible from that part on. But NOTHING in between, from when you press INSTALL until the app runs, can be influence by the developer.
Also, recently there were multiple issues with apps being or not being installed during different occasion, I believe you might be one of them.
btw seems others users do have same issue on other app
