Firefox for android doesn't connect to cloudflare dns using the DoH protocol

I've configured my android phone to connect to cloudflare dns using the one.one.one.one server. When I go to https://1.1.1.1/help in Firefox for android, the page shows that it cannot use the DoH protocol, but Dot works. That wouldn't be too much of a problem but, since Firefox has rolled out ECH and it requires DoH, Firefox won't be using ECH. Is there a way to fix that. Thanks.

P. S.: I should point out that when I visit cloudflare's dns help page chrome for android does use DoH.
