Notifications not working
Notifications pass through both Filltr’s own settings and your device’s system settings — check both.
In the app
Settings → Notifications controls what you get notified about (messages, likes, views) and whether previews show the sender and text. A muted chat never notifies — check the chat’s menu if one conversation is silent.
On your device
Android Settings → Apps → Filltr → Notifications: make sure notifications are allowed and the channels are not silenced.
Battery optimization can delay notifications on some devices. If messages arrive late, set Filltr’s battery usage to "Unrestricted".
Still nothing?
Force-close and reopen the app once — this re-registers the push connection. If it persists, contact support@filltr.de with your device model.
