Apps Multiple rewarded videos in a row allowed?

I couldn't find any information about this.

Can I display multiple rewarded videos in a row or does that violate the terms of use?
Are there limitations or other restrictions?
If it's not allowed, how long should be the delay between two videos?

Thank you :)
Are you talking about embedding advertisement videos in your app? Honestly I can't talk about how many videos you can have play back to back but I would suggest not doing that. It screams you just made the app for monetization and users will not utilize and delete your app.

Always live by "less is more".

Hope that helps.
