I am new to this - seems very exciting & I can see possibilities . . . been getting email for months.
But hold on there 15m, 5min 1min polling - you've got to be kidding?
I create a subscription - zap it to Sheets . . . actually not . . . wait 15 min
Customer waiting to login with his new app which is also zapping the spreadsheet to verify the new license is OK.
Waiting forever! - Its a non starter.
Is there any work-around or decent speeds for the future - I’m thinking 10s
