Amazon Prime Video on SmartTV

I have the tvision hub google tv device and tmobile home internet.  Everything worked fine on my tvision hub except amazon prime.  I enabled developer mode and sideloaded cloudflare's 1.1.1.1 app, part of their zerotrust suite.  With this active in the background, amazon prime works fine--well, a little slow to load the video, but fine once loaded.  (I'm not at the device now to check, but there are two options with cloudflare under settings:  one is "gateway with DoH" and the other is "Gateway with WARP."  I think you want to select the former for this to work, but you may need to experiment.  This is a free solution that doesn't require any other hardware running.  (I happened to have a usb c device that allowed me to plug a usb drive into the Hub and sideload cloudflare that way (Cloudflare doesn't show up in the Play store), but I guess there are ways to download an .apk file from a cloud account.  Also, I have a cloudflare account, but I don't think you even need to create one to use the basic 1.1.1.1 dns service.  Finally, I'm not sure why this works, but it does.  (Also, I tried a vpn approach with zerotier, (also sideloaded) but that didn't work.  I think amazon prime sniffs out the vpn approach and doesn't like it.
