NextDNS and Windscribe

Did anyone succeed to get NextDNS working with Windscribe new iOS beta?

Adding DoT (xxxxx.dns.nextdns.io) or DoH (https://dns.nextdns.io/xxxx) endpoints from NextDNS webpage doesn't work.
Non issue with AdGuard though. 
I also tried the DNS IP but whatever my input is it ended up on Windscribe DNS.  

Any suggestion?
