WARP Client blocking specific app

Hi everyone!
I have a specific app from my gym that I use to see my workout program. When WARP client is enabled I can’t login or even use the app if I was already logged and if I disable WARP client the app runs without any issues.
In the gateway logs I can see all the traffic from the app as “Allow” for DNS queries, Network and HTTP. No blocking URLs or protocols and ports from that app are shown on gateway logs.
I’ve tried to re-enforce firewall policies placing app URLs inside a “Allowed URLs” list and testing some policies, but I got no success.
Does someone have any idea how to handle this situation?
