I have an end user who would like to access their PC using the mobile app. I’ve installed Splashtop for RMM on their Android. They’re able to log into the website, and click the icon to access their computer. The Splashtop App opens up, and looks like it will connect to the computer, but then it closes. Their phoner is a newer Samsung, and I’ve checked for updates and reinstalled the app. The behavior remains.
Did you try it on your device? Honestly, it’s not worth troubleshooting someone’s personal cell phone IMO unless it’s happening on multiple. But I also have a Samsung and have no issues launching a remote connection on it.
