Why does the web client / the desktop app lose the connection as soon as the mobile device goes into sleeping mode or is locked?

Android: If this symptom occurs, either push notifications aren’t working properly, or there is a problem concerning background activity. In other words, mobile devices cut the connection to the app in the background after a while. Please follow the troubleshooting instructions for Android (Samsung, Huawei, Xiaomi, Sony, OnePlus, Gigaset, Ulefone Armor, Doogee, etc.).

iOS: If you’re experiencing issues in relation to the connection of the web client / the desktop app and the mobile device, please refer to this FAQ entry. Should the problem persist, push notifications might not be working properly. In this case, please follow the troubleshooting instructions for iOS.
