I can't add my phone number in the tab add phone number in Galaxy Sharing. I see my number on the list I select it, click add and nothing happens it takes me back to the beginning I can again select my number click add it and again nothing happens. My wife got zflip4 and got same problem but she got message something went wrong try again over and over again. We can't use Samsung sharing features like, sharing location because we both can't add our numbers. In my Samsung account our numbers are correct, software is up to date, cleared cache, done hard reset and nothing helped. I did everything consultant told me and still no solution.
