I am sorry to hear that the plugin didn’t work on your site as expected. Although I see you have not opened a support thread with us so we could not help resolve this issue. There could be a conflict with another plugin or another cause like settings misconfiguration.
If the issue is coming from one of the above, we would love to look further into the situation so we can create a better product.
Kind regards,

I’m sorry to hear that you’re having issues with running Hummingbird alongside Osmosis theme.
I did give it a quick swirl on one of my test sites and I’m afraid that I couldn’t replicate the issue there, I was using Osmosis theme and before configuring HB my page load speed was around 5 seconds and it was cut to half after HB was up and running, and my page speed score jumped from 23 to 64, so it seems that there’s something specific on your installation affecting Hummingbird.
As for stating compatibility, I’m afraid that that’s not really possible as there are over 40000 plugins and 5000 themes on www.remarpro.com only, and with all the other premium plugins and themes out there, this is something that simply couldn’t be done.
Best regards,
