Ionic Image Loading - Domain Issue?

I have an Ionic PWA that I am hosting on Firebase (, that used google map services to load a list of locations near the device along with a thumbnail of each location. I am testing on an Android device and everything works great.
The Issue…I have a domain ( that I have rerouted the A records to point to When on my Android device and point to the application still functions as expected except images (like the thumbnail from google map services and any image that I choose with the apps functionality) do not load into the application. I thought this was some sort of HTTP Header issue and added ‘Content-Type-Security’ with a value of "img-src * ", but that did not work.
Any help would be appreciated.

My DNS is a bit rusty, but I thought one used CNAMEs for this, not A records.
