Hey there Chynarose_18,
Thanks for taking the time to reach out here in Apple Support Communities. From what I gather you’re unable to use lyrics as expected, and you’re having trouble loading search results in Apple Music. Is that correct? I’ll be happy to help.
First please keep in mind that lyrics aren’t available for all songs. Explicit lyrics and lyrics search isn’t available in all countries or regions. With that being said do you know if this happens with multiple songs selected? Have you been able to view lyrics for the affected songs previously?
Have you tried restarting the iPhone to see if that helps? Have you been able to test over cellular and different Wi-Fi networks?
Are there any restrictions configured on the iPhone? Take a look at the article below.
Use parental controls on your child's iPhone, iPad, and iPod touch
I would also recommend creating a backup and updating your version of iOS if need be. That can also help isolate the issues a bit further.
Update your iPhone, iPad, or iPod touch

Take care.
