Question about sonokids apps

iOS and iPadOS Gaming

Hi guys.
Just wondering does anyone use the ballyland apps from Sonokids?
And is anyone having issues?
The issue I'm having is when I go into the ballyland magic plus app or the VO lab app and when I turn off voiceover and turn on the self voicing it turns on visually but I do not hear speech.
Is anyone else experienceing this issue?
This is happening with ballyland magic plus, VO lab and the ballyland roter app.
I think the cosmo bally app works fine atleast when I last tried it it worked okay.
