I upgraded to 2.3.1
I am using only PayPal as a payment method.
new orders are not showing in the orders grid in Admin > Sales > Orders
when I check PayPal summary I can find the invoice number so it is created in Magento but not showing in the grid
I already tried to change
Store > Configuration > Advance > Developer > Grid Settings
Enable / Disable, flush cache, reindex, but not working
update: When I check
sales_invoice there is no recent invoice! But in PayPal summary I have the invoice number and items!
