I am kind of stuck, i have migrated my website from Magento 1.9.4 to Magento 2.3.5-p2
Now i am having the following issue, a new customer or guest can order just fine.
However when a existing customer from the migrated Magento 1 enviroment logs in all goed fine up untill the selection for payment methos and once the checkout button has been pressed its an neverending webpage loading.
I have checked Auto_increment and i see mg_sequence_order_0 ( not moving up in number )
And there is a second one ms_sqeunce_order_1 in my Phpmyadmin where this auto_increment number is gaining which each order.
Does anyone have ran into this issue before because i am stuck and dont know wether i should change these values or delete one entry. my goal is to have migrated customers able to place orders after login and go through with the payment process
