I have attempted to contact support repeatedly via both chat and email for several days, with no response. This level of disregard for customers is unacceptable, especially for an app that handles crucial aspects of an online store.

While the app may have potential, the complete lack of support makes it unreliable for professional use. I would advise developers to drastically improve their customer service if they want to be taken seriously in the Shopify market.

Unless you are willing to troubleshoot every issue yourself, I suggest looking for alternatives with more responsive customer support.

Customer support is the worst. I have been trying to reach out to customer support for the past two months, but there has been no response. I have never experienced this kind of careless support from any app. I am facing cache issues, some functions are not working on some devices, and some features are visible on some devices but not on others.

Scammy and Unreliable – Avoid at All Costs! Charged my account after I uninstalled and I have tried to send messages to get help with fixing and no help and it's almost been a week. It's messing up my shopify website and other billing subscriptions. Do not download and install!!!!! Save yourself the trouble and find another app. You deserve better than shady billing practices and ignored support requests.

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.

Altdaten im Quellcode nach löschen der App. Das führte zu verschiedenen Shop Fehler. Es wurde unteranderem kein Favicon mehr angezeigt und andere Apps wurde im Hintergrund blockiert (z.b. Klaviyo). Damit ist man praktisch gezwungen, die App dauerhaft zu nutzen, weil es sonst zu Problemen im Shop kommt.

It simply make all your images to fake board at the first loading, then make lazy loading to img, BUT in may cases java have failing and images not show up. page speed goes up immediately but it totally ruin the view overall. second thig: it makes 1K back links from one IP.
And support is not answering at all.

"I'm extremely frustrated with Flash Speed Optimizer. As a paid subscriber, I expected my store to be fully optimized, but there's still a 30% unoptimized score on mobile. This is a serious issue since most of my visitors come from mobile, and it's directly impacting my business negatively. Despite multiple emails and chat messages, I've received zero response. This level of neglect is unacceptable. I demand immediate action to optimize my store and compensation for the damage done to my business due to their inaction. Do not trust this app if you value your business!"

Very expensive and misleading, money pit. It does what they say, but at an unreasonable and unexpected price, way above $19.90 they advertise. Also, they raised their base prices without warning, when I installed, the base price was $9.90

App seemed to be doing a great job, then about 2-4 weeks ago the page speed dropped. I've tried three times to contact support, but no one has gotten back to me.
