I followed the tutorial closely, but in Step 4, when I click on my custom payment function within the Payment Customizations section, Shopify redirects me to the app embed home section. After going back to Payment Customizations, the list of selected payment functions appears empty. Has anyone else encountered this issue or have suggestions on how to fix it?
Hi @octenda 
Speak in specifics when you have specific issues: how-to-ask-a-good-question
WHICH tutorial: Remember other people aren’t mind readers “I followed the tutorial closely” doesn’t mean anything on the internet with millions of tutorials… one could just assume a guess but that runs high risk of wrong answers wasting everyones time.
Be considerate to YOUR time and others time and put in the effort in advance to communicate what other people need for understanding your problem without them having to dig it out of you.
If you are developing a custom app, these are the app recommendation forums not app development forums

Hi, I’m new to the community, and I’m working on improving this issue. In the meantime, I came across this related issue, which I think might be connected: Payment Customization Extension App is not working
