Thx for that Sean,
I found it difficult to find any clear info using search engines, as once the abvr. "VPN" Is used, the results are all adverts or honeypot reviews. I previously found a similar situation to you, I retested today to confirm. and found - pic CF1
However after I installed the latest version of the app,
My attempts seemed to show that the cloudflare DNS is now in use, - Pic CF2
I lost access to the WARP+ function of the CF apk - I mistakenly reset it when looking at the logs!, so couldn't test further.
Also if a VPN is active on the Hotspot Provider it seems unable to provide an I.P. to the Hotspot Client, but if I momentarily disconnect the Provider VPN an IP is assigned to the client. A VPN will then operate successfully on the client, I used the Nord Apk.
If I understood your answer properly this is the way to do it?
I'm probably wrong as I'm figuring it out as I go.
A huge Thank U for the Editor site - I am amazed at your generousity
