Genau das was ich gesucht habe, es waren nur ein paar Klicks nötig und keine Programmierkenntnisse. Mein Pagespeed hat sich teilweise um 50 Punkte nach oben korrigiert!

The app stopped working 3 weeks ago, blank screen. Cleared cookies, cache and even changed browser and still does not work. Tried in a different store and and it works just fine. So the issue is only in our store... Being reaching Clauma support via e-mail and via Shopify form and no answer for 3 weeks already, the app used to work fine but the issue and the lack support will make me delete it. Would not recommend right now.

UPDATE: After some months it seems that support has reappeared and the app has being updated. It now works as expected.

UPDATE:
They replied and advised me to uninstall the application.

After about 15/20 days they contacted me to tell me that the problem was solved and actually now it works very well.

Thank you

The application is great, but the support service is terrible.

I have a small problem with the app, the dashboard no longer works for me.
I wrote him 3 emails and 2 messages through Shopify, a week later still no one has replied to me.

Finally an app that works! We have a large site, onshorecellars.com, with thousands of products, collections etc. This App is the only one that has worked in 4 years of searching. I have paid thousands for developers to speed up our site with nominal increases in lighthouse scores. We averaged - 35-42. 5 mins altering setting this up we are between 91-93. THANK YOU THANK YOU THANK YOU!!!!

The app did nothing to improve performance. When I attempted to uninstall, it left other apps not performing on my site (my new customer form and product reviews no longer function). Shopify confirmed it was due to code from this app screwing up those features. Now I'm left to sort that out because customer support is not responding.

Terrible support, due to no support, removed the app and it left code in the site that broke features in my store. Had Shopify support involved with the issue and they responded several days later "we refunded the customer" leaving no regard to get the code removed from my website.

I am sorry for not getting back in time. As of today, your issue seems to be solved. Please let me know if we can help any further.

Really disappointed in the support with this app. I sent two emails to support, no reply. I joined the slack channel back on 7/11 - Marc responded & requested access to my site, which I promptly approved. Since then - no response. My site speed dropped dramatically and I started to get errors in SEMrush. Was just looking for a little guidance, and Marc seems to be overwhelmed or just MIA. Fine... but your app isn't working and I'm not going to pay for it.
