I installed Messages + but have no sound or vibration on my iphone 12 pro max? I have tried everything.
Are you referring to notification sounds/vibrations? On my Android phone there are notification settings in the app, selecting Settings and on my phones' Settings, there are Notification options for apps, including Message+. Do you get sound/vibration notifications for other apps? Have you tried uninstalling/re-installing the app?
Waggy33, we want to ensure you can obtain notifications as needed. When you go into your iPhone Settings and select Message+ and Notifications, is Allow Notifications set to on in green? Is Sounds also on under that setting?
