What is the issue you’re encountering

My customers have been having issues with accessing my website via Facebook browser only on android devices. Facebook rewrites the URL to: https://l.facebook.com/l.php?u=https%3A%2F%2Fborderscompetitions.co.uk%2Fmy-account%2F%3Ffbclid%3DIwZXh0bgNhZW0CMTAAAR6zAggkb59ECFot5dubpwCtkmv3H6HSN0-7c4a8ohfd0f8hFRVBF0Q-8L4TVA_aem_KG9QUwIZe-rTqJ1fnXvKMA&h=AT30kmo1kXXOMiJ5wi9zH9pWXAhZYufX1WZDq6srbSvqj9d7YMNqtP739HdovrPRJ8cM5Ll0lZprbcRLLwDN0zHBJi9q4ZYMqhM1iUqFs8QuGjG3ksPcCvN8EXaw0BMI_clbg9FIONhpE2tjbEEZTg . I have created security rules to skip all Bot fighting etc and still issues. The user is shown a grey screen with two buttons, continue to website or go back and no buttons work, not sure how to fix this but another website owner disabled cloudflare and it resolved the issue.

What steps have you taken to resolve the issue?

Disabled all security rules

What are the steps to reproduce the issue?

Opening our website via facebook browser on Android devices.

Can they access your website from another browser on the same device?

Such as e.g. Firefox and/or Chrome?

What Android version(s) do you(r customers) see this problem with?

Yeah they can tap the 3 dots and open in external browser it will work fine, just facebook browser showing that image. All versions. Very confusing as i cant replicate it!

In that case, you will need to look in to the case together with Facebook.

As it is working fine outside the Facebook browser, it appears to be something with their app, which Facebook will need to look in to.
