Page Speed Optimizer LCP & CLS

It's not working even on Shopify Dawn theme...
He didn't even tried to make it work. Each consequent "fix" will decrease my store speed to around 50.
Even if the app doesn't work, they still charged me.
The first answer was a recommendation to just uninstall the app, which say a lot about their ethics.

No customer support whatsoever. I am not sure if the app even works

Hello,

We eagerly installed this application with high hopes. We made all the adjustments, but apart from a 1-2 point improvement on our website, there hasn't been much progress. We've been trying to reach the support team for two days now, opening tickets through the support section and sending emails to their addresses, but we haven't received any response or assistance whatsoever. Frankly, when I read the reviews, it doesn't seem like this at all. Either the reviews are fake, or they no longer care about this application. In short, the application is not functioning, and moreover, you can never reach the support section.

installed the app and nothing has changed, contacted customer support, no response at all.

I haven't seen any changes with the app installed.

If you're considering using Speedien Core Web Vitals Plus, I strongly advise against it. This app simply does not work as advertised and it has been a source of frustration for our business. We have been paying for this app for years, yet it has never worked properly.

What's even more disappointing is the complete lack of support from the vendor. Despite numerous attempts to reach out for assistance, we have never received any meaningful help. It seems like the vendor is more interested in taking our money than actually providing a functional product or any support.

We have had enough of the excuses and wasted time and money on this app. In fact, we are taking action and reporting our experience to Shopify.

In short, DO NOT INSTALL Speedien Core Web Vitals Plus. It's a complete waste of time and money.

1 CONTESTACIÓN: Llevo unos meses con la opción de pago y esta es mi experiencia con esta aplicación y soporte.
Cuando instale la aplicación y el soporte amablemente la configuro por nosotros teníamos 65 de pagespeed, notamos una mejoría de velocidad de 15 p y la web se puso en 80 de PS, pero esas métricas han durado muy poco y desde 2 meses esta cayendo hasta un 49 de PS actualmente, Pero la frustración no es solo la velocidad de carga es que el soporte a pesar de ser una aplicación de pago el soporte en nuestro caso es nulo, le hemos enviado más de 3 emails y no hemos recibido contestación alguna y la web sigue cayendo en velocidad, experiencia de usuario y evidentemente en ventas. Sensación de la aplicación y el soporte: Frustrante y decepcionado, nada recomendable. 2 CONTESTACION: Creo que con la respuesta a mi reseña 1 intentáis confundir ya que no puedo malinterpretar mal tus respuestas en soporte por que no habéis realizado NINGUNA respuesta después de 3 veces que me he puesto en contacto con vosotros, Respecto al informe al que me envías como puedes apreciar da errores de lectura en la versión móvil y muchísimos errores en la versión pc.
Por favor, que el soporte no conteste en un servicio de pago es lamentable, pero mas lamentable es querer confundir con respuesta banales, para confundir a los siguientes interesados en instalar la aplicación

Updated: I've emailed support@speedien.com on Aug 4 but got no reply ---------------------- The app is not working and the team doesn't reply to my email! I tested website speed after enabling but the result still doesn't past the Google pagespeed test

Yes, it boosts your speed but it damages your code. Lost of my rich schema results. Uninstalled the app and it is fine again. Dangerous app!

broke my site just after installation. 10/10 for their support though they got me up and running again very quickly.
