The team continues to make progress on this. We will share more details as we have them.
Great performance and user experience remain a topmost priority for us. Application launch time has seen improvements in the recent build. We will continue making improvements across the product including channel to chat switching and overall resource consumption.
This feature is planned and we’ll update as we know more details.
Regarding recurring meeting invites, the meeting link is unique so you can use the same meeting link for all instances.
In addition to being available on Windows & Mac, we have released iOS 2×4 (mobile) and 3×3 (iPad), along with Large Gallery and Together Mode. You will see these options with the latest version from the app store. We are targeting availability for Android clients (mobile and tablet) this quarter as well.
