How to debug on mobile browser?

From what I understand, debug mode is only available for desktop.

I have an issue where a certain workflow works perfectly on desktop, but does not execute on a mobile browser (either Safari or Chrome). This is a workflow that involves sending a token to Stripe using the Stripe.JS plugin when a user makes a purchase.

Looking in the server logs, again I see that the workflow executes as expected on desktop, but does not execute at all on the mobile browser

What are some suggestions for investigating the issue, since I can’t use debug mode on mobile?
