I appreciate you reaching out about this, and also posting your question in our Shopify APIs and SDKs forum here. That forum is typically the best place to get help with apps you've developed yourself, so adding your question there is definitely a good idea.
Based on the post you linked, I can see that you've already tried out multiple browsers, and have cleared your cache and cookies on your browser. These are great steps to start out with, and I'm sorry to hear that they didn't resolve things for you.
As a next step, I recommend contacting our Support team about this directly via our Help Center using this link. Once you log in to your account through our Help Center and submit a support request, our team can help look into this further over live chat, email, or through a callback.

To clarify, are both you and your customers receiving an error related to cookies when trying to open the app you developed? If so, I recommend following the steps I previously shared here:
Since you're the developer of this app, and due to the fact that both you and your customers are receiving this error, I'd really like to have our Support team look into this situation further. That way, we can test things out and see if we're also able to replicate this error on our end.
To get in contact with our team, please visit our Help Center, log in to your account, and submit a support request with us there. This will authenticate your account so that our Support team can troubleshoot this error, and speak with you in more detail over live chat, email, or through a callback.
