Clarity needed on Firebase Remote Config rate limits

[nrajput05]

Based on this documentation link, the old rate limits are 5 requests per 1 hours. Also this is for android, if I open flutter's documentation it doesn't mention the 5 request per hour limit anywhere. I have a few questions around it. Please help !

1. The documentation further says that limits have been improved but what is the new limit?
2. Is this rate limit for a single device?
3. Based on this limit, if I set minimumFetchInterval to 12 minutes then will it be a safe considering each request is 12 minutes apart so 12*5 =60?
4. If above is true, let's say If I have at least a million users of my app opening the app daily at 9 AM and the app triggers fetchAndActivate on app launch. Considering that the cache age is already expired overnight, will this result in throttle based on the volume of the requests?
5. My assumption is that before a throttle exception there would be atleast one successful remote fetch per device. So its not like there are certain devices that never got the remote configs on their first launch.

Please clear these doubts to ensure whether Firebase Remote Config suits a production heavy use case or not.
