Does your video use end-to-end (E2E) encryption?
No. At this time we're only using Group Rooms for connecting individuals on our platform which don't support E2E encryption. Many video services only provide end-to-end encryption when users are directly connected to each other, which limits the size of the call to 2 or 3 people. If Twilio adds support for E2E encryption to their Group Rooms, we should automatically inherit the update.
