Route 66 problems with jAMP plugin

I use a plugin jAMP and when enable System - Route 66 plugin AMP pages are not valid because have been route to the main page. Is there a way to fix ?
My amp pages are using amp suffix like https://domain.com/amp , https://domain.com/article/amp and so on 

The problem is that all amp pages are redirected to the non amp pages.
Thank

If I remove the redirect option i will loses the best part of your plugin: elimination duplicate content.
The Jamp plugin doesn't appear in the exclusions options of Route 66
Thank

Somebody had the same problem and the extension developer answer was:

I can't answer because route 66 it's not a plugin of mine and I don't know how it works.

You must firstly determine the exact reason why Route 66 invalidates the Google AMP format.

If it adds some extra html code to pages that is not compatible with AMP you could get rid of it using Jamp exclusions settings.

If instead it's a problem due to routing itself probably is a different question, but it would be better asking to their developers. After all this is an issue strictly related to Route 66 not to Jamp

No there are no workarounds or something to do in the jamp plugin, the only possible solution is that they add support for AMP URLs in the Route 66 plugin, this issue was already discussed here more than 1 year ago.

There is no way or possible workaround to have this working on the JAmp side, everything is up to Route 66 plugin due to the fact that it overrides the standard Joomla routing.
It would be better to ask to the developers of Route 66 if they can add support for AMP URLs that will be more and more common in future. This is an issue strictly related to Route 66 not to various AMP plugins used.

Yes that is:
https://domain.com/amp
https://domain.com/article/amp
https://domain.com/article/idnumber-alias-nam-name/amp
https://domain.com/categories-name/amp
https://domain.com/categories-name/idnumber-alias-nam-name/amp

and so on
