Plug in Speed ‑ Maximize Speed

Not really impressed. day 3 of the free trial, it won't work and show me my dashboard. It's still saying it's optimising my images which should not take 3 days to do. I have emailed and no reply and I have sent two support requests via Shopify which resulted in 2 automatic responses.

I should not have to leave a bad review to try and get a response. All I want to know is if this is going to work or if my money will be better spent elsewhere.

Please help
