I noticed the same behaviour like the OP with build 981 on two different devices: Lenovo Tab 8 (TB-8705F), Android 10 and Samsung Galaxy A52 5G, Android 13, OneUI 5.1
I've tried the options custom URL, Google, Google (Web) with no luck.
On both devices a default browser app is set.
I don't want to fully reinstall PA.
If I remember correctly opening the preferred lyrics app worked with one of the last builds.
