Unable to send messages when captive_portal is blocked

Hi Matrix-Team,
I really like your work and especially your messenger Element!

Myself I am using Android 9 without Google services due to I am also using AFWall+ to block Google services. First I was confused about why Element is not sending my messages, because in Riot everything was working fine.

I was blocking captive_portal_login which is connecting to a website from Google to check my internet connectivity.
Due to it reported that I have no internet access, even if I had internet access.

Now I just turned off captive portal detection with this command `adb shell settings put global captive_portal_mode 0` and Android is telling that I have internet access.

When captive portal detection response with "no internet access" even if I have internet access, I am not able to send messages in Element. In Riot this was working fine.

So captive portal detection is necessary for Element now?
In a worst case scenario no one (except technically experienced people) would be able to send messages in Element if the captive_portal website from Google is down, even if the matrix home server is online. I would recommend to check internet access with the matrix home server which is in use.

Best regards!
