If you have a version 2.6 or older the app can't update automatically, and you would have to;
Remove the screen from my.playsignage.com/screens Uninstall our app on the Raspberry PI Download and install our app on the Raspberry PI (Download it here: https://playsignage.com/setup/raspberry-pi-digital-signage/#download) Add a new screen in my.playsignage.com/screens using the code displayed on the screen.If you have a newer version of our app it should automatically update every time we release a new build, however this doesn't mean your RPI will update the same day we release, as we have thousands of RPI's around the world so we have to use a technology called staging.
If there is a feature you're missing and you need it now, you can reach out using our live chat and then we can force an update remote.
I hope this helps.
