I'm pretty new on the app development on Shopify and I've been following the tutorial on Shopify page which has been very helpful.
However, I've been facing an issue when installing my app on multiple stores using the same browser. If I go to the partner site and click "Install on development store", it works for the FIRST store. However, if I try the same on the second store (or anything after the first one), it gives me an error of "The page you’re looking for couldn’t be found"
Interestingly, if I copy and paste https://YOUR_NGROK_ADDRESS.io/auth?shop=YOUR_SHOPIFY_STORE.myshopify.com on the browser to install, it works fine for both.
I suspect it's related with session information that's being used inside verifyRequest middleware but I'm not sure how I can fix the issue. I was wondering if someone else experienced the same problem and found a solution.
If it's already discussed else where (I've been looking but couldn't find one), please let me know as well. Thanks a lot!
