is_amp_endpoint() produces errors.

I am using the is_amp_endpoint() function in my code and I had multiple reports from customers who said recent updates of AMP WP broke it. Someone told me another update fixed it and then another update brought it back. So I like to ask what is going on and if I can use a different future proof way of detecting amp without running into errors.

#986 (comment) speaks of a new way instead of this constant. I saw many issues around this including one where someone closed it claiming that is_amp_endpoint() is not part of this plugin when it actually it, found that very strange ... so not sure where to start.

The is_amp_endpoint() function has always been part of this plugin.

You are using the accelerated-mobile-pages plugin not the amp plugin. Please report your issue on their repo: https://github.com/ahmedkaludi/accelerated-mobile-pages

@westonruter I am not using anything it was from a customer and I copy pasted just the the relevant portion of the report here. But thanks I failed to spot that so he is just running the wrong plugin, I did never intend to support that so I guess there is nothing wrong at all.
