[Hummingbird & Smush.] Are there known problems with using Hummingbird and Smush on Godaddy Ma

I have Godaddy Managed WordPress hosting. I am currently testing Smush at least for Image Compression. Using other plugins similar to Hummingbird and Smush have had problems with Godaddy Managed WP’s caching and cdn. I tried searching support for settings to enable/disable but am not finding information for avoiding problems between above mentioned plugins and Godaddy. Is there someplace I can read up about using these plugins with Godaddy?
