Hello @prayag922
AMP is a web Component framework that uses a very strict set of rules, to ensure good performance AMP pages must follow those rules, those rules are defined by AMP validations
You can learn more about AMP validations in AMP documentations
Plugins such as Astra Pro, Rank Math (Recent Updates in Rank Math) , and Lite Speed are adding AMP invalidations and are not AMP compatible.
Rest assure that those invalidations are been removed the AMP plugin but it also compromises the features that plugin adds on AMP pages.
AMP plugin adds site scan feature and Validation Tool to find and help users and developer those plugins.
What you can do?
- Contact Plugin author ask them to make their plugins AMP compatible
- Look for mini plugin or extension that can help you fix AMP compatibility.
- Look for alternative from AMP ecosystem
Regarding performance
As I asked in my previous response the major issues regarding AMP performance (mobile performance) are web stories images that are not properly sized for mobile screen
We hope this helps
