Can't retrieve message or photos using Your Phone and Android Phone

I have a Samsung Galaxy S10 [Android 10, June patch level]  with Windows 10 Pro v1909.

Your Phone [YP] [latest on Win 10] and Your Phone Companion [YPC] [latest] on Android. Android phone linked to Win 10.

For whatever reason, if I want to send a message I have to manually type in the phone number. I can then send out a message but it keeps on saying "Sending" in YP even though it has shown up on my phone.

For pictures, I can't retrieve pictures from my phone to YP. And no notifications as well.

Interesting that the Phone Screen feature does work.

In mms.png, I can't seem to find the setting on my Android phone.

See attachments.

Thoughts?
