Amp Pages and bookmark problem

### Description

when I search on the Google search engine and click on the results, the pages that open with "amp" , when saved in the favorites, are no longer supported after some time and I lose the search result while the article is still present on the site where it was but not in the "amp" version, this is risky because the amp results are not reliable to be archived: sometimes it is not possible to trace the title of the article that had been archived in the favorites making it impossible to search for that specific result/text/ news. I hope a solution is found between google-amp-sites owners. Thank you

### Reproduction Steps

Android > Chrome browser > Google search > click on result > "amp" page opens > bookmark It > ....more time after.... > click on the that bookmark: amp page is no more avaible > and often It Is impossibile recognize the title > so search result is lost

The issue provides only an Android, Chrome, and Google Search reproduction, with no repository file, test, or logs identified. Start by determining whether the reported bookmark and retired AMP-page behavior is within this project's scope. A useful outcome would require a defined repository change and a reproducible test, neither of which is specified here.
