it’s been great pleasure for your answer, but I think I did not elaborate my issue correctly. let me try once again,
I’m developing a shopify app in react and Symfony (php) in backend.
Let assume i had 2 pages in my app, Dashboard page and Wishlist page.
I use session token(JWT) for authentication.
when I tested this app in incognito mode (third party cookies are blocked).
first time i load app from shopify app listing, it loads correctly and everything works fine, and i redirected to Deshboard page.
next i click on wishlist page and then reload the iframe, i got appbridge shop origin issue, because without cookies i am unable to get shop origin becuase shopify did not provide shop or host details.
I solved the cookies problem in my Shopify reactJs application. I use Reactjs for it.
Btw, I added shoporigin and host in every routes of application, so that i can get required shoporigin and host parameters without saving them in the browser cookies.
