Sound not working on iPad 7th generation
You should probably raise this as a bug in the usual way. It won't really get progressed if it's only posted in these Developer Forums.
You need to raise each issue you find separately at https://feedbackassistant.apple.com/ You can post the FB numbers here if you want, so that others can link to them.
We use these forums to ask for help on coding our apps; not for pointing out bugs in a beta version of the software. Please report bugs in the usual way.
