Hi, I really appreciate your great work. But I have the same problem since Astra 4.3.0. Two headers are loaded. This leads to massive CLS. Page speed drops from 99 to 60. The CLS increases from 0.00 to 0.6.
I’ve optimized my site well, but can’t find a way to achieve acceptable performance since 4.3.
To generate a separate cache for mobile view is the wrong practice. By the way, Astra itself also has massive problems with the header and CLS: See here: https://pagespeed.web.dev/analysis/https-wpastra-com-blog/cljjix25z5?form_factor=mobile
Do you care about the page speed rating of 13?
