Recently installed Message Plus on my iPhone 8 however I can’t figure out how to change the sound for incoming text messages in the Message Plus app. Help!!

We would love to see you enjoy the right tones on the Message+ app! When going to Settings>Sounds and Haptics>Text Tone, does changing this tone allow Message+ to recognize it?

Unfortunately no. When I change the tone in Settings, the change only applies to the original text app on the phone. The Message+ tone remains the same.
