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.
