Switching from deprecated commerce mobile app to squarespace, no more "sell now" button

Up until recently we've used the commerce android app to take Point of Sale credit card payments. The commerce app has been deprecated and it pointed me to the squarespace app. The android squarespace app has a commerce tab but no longer has the "Sell Now" button. Weirdly, the iOS version of the squarespace app DOES have the "Sell Now" button. How do I use the android app to do Point of Sale?
