Qatar Airways Privilege Club - BizFlex Fare Rules

Was trying to book a fare with the most unrestrictive fare rules.

However, when I tried to see the conditions of BizFlex for my booking, it's just a blank page and click on the details leads to an error page.

Wondering what is the general restrictions like.

I'm ticketing out of CMB. Are the fares fully cancellable and no surcharges for date changes?

Where are you going? When? For how long?

Found the rules on Expert Flyer. But it's also showing properly on QR website now.

Biz Flex - No Change fees, $50 Cancellation,
Biz Restricted - $50 Change fees, $100 Cancellation
