My customers cannot checkout on mobile- invalid phone and/or address

Customers are unable to check out on mobile The checkout cycles through several iterations of errors:

automatically asks for phone number and sends when I made that optional.
does not recognize valid 10-digit phone numbers with the country set to US (1) - this happens when autofilling or entering manually. if you try to checkout as guest it still says invalid phone number
does not recognize valid addresses both using the google map and entering manually
I have recreated this all on my phone and am experiencing the same issues

Apple pay does not work because my address is invalid there too

On my laptop I was able to complete an order.
