The Chrome extension used to work wonderfully for creating new RingCentral Meetings from right within Google Calendar, but as of late last week, the option to create a new meeting has simply disappeared - I now only have the option to "Add Google Meet video conferencing".
I opened a case with RingCentral support (10754179), and was told that this was a result of a recent update on their end, but was told to post something here as well.
I'm running Chrome version 83.0.4103.61, RingCentral Meetings version 19.4.152079.0420, and the RingCentral Chrome extension version 4.2.10 (all the most up-to-date versions that are available to me).
Software updates, removing and re-adding the extension, refreshing pages, etc. don't do the trick.
