AMP Failed

Hi,
First of all Happy New Year!
Second i need a little help here please. I didn't know where to post this thread to ask for help so i did it here..where i think i could get good answers.
I have installed the AMP plugin for faster page speed and according to google better rankings ...but i get on some posts this error
The author stylesheet specified in tag 'style amp-custom' is too long – the limit is 50000 bytes.
First detected: 30/12/2019
Status: Error

I tryed to solve it but with no luck.
Does anybody know what should i do specifically? Thank you!

I've used both AMP from AMP contributors and also AMP for WP - Accelerated Mobile Pages for WordPress By Ahmed Kaludi and Mohammed Kaludi . Both are the most used AMP plugins . I have the same problem.
