Google Meet App is not fulfilling Webinar

Today I attended a webinar through "Google Meet" App, organized by

Albertian Centre for Human Resource Development & Research 

St. Albert's College (Autonomous),  Banerji Road, Ernakulam 

Kochi - 682 018, KERALA, INDIA.

Topic was:- Action Research for Teachers.

Problems are:-

1. Sound quality and video quality is very poor.

2. Students are complaining about this in Chat box rather than studying.

3. Prof. Amita Pandey Bharadwaj was presenting. But many times she was not showing PPT.
