Cloudflare Warp Android app not switching between DOH and Gateway mode

Hi all

I am struggling to figure out why my Android phone, running the Cloudflare “ WARP” app does not want to switch between DOH and WARP mode. I enabled the Mode Switch selector so that I can switch between the 2 options, but my device always reports as “warp+doh” under devices.

Not sure if this is a bug on the website or a limitation of the free WARP account?

Any help will be appreciated.
