Q: For the quota: I've paid a tier 4/400 credits but allowed to use only 200, which is less than a Tier 3. Am I wrong?
Hello, I purchased Jogg AI tier 3, then upgraded to tier 4, JUST to get more credits. 
Now with 3 seats, we're just starting to use Jogg. The quota is 50 per week. So, each month, we will be able to use 200 credits out of our 400, which is less than Tier 3 credits.
We're actually using the image-to-video feature. The max duration per generation is 10 secs. This means that we will be able to generate a max of 8 mn 30 secs of video per week with this feature, if we ONLY use this feature, otherwise it will be less. Question: Are you trying to crash shorts YouTube channels?
I saw your answer stating that unused credits are returned to the pool and therefore never lost. But never lost for whom? Because those who purchased them are not the ones using them. Why isn't the total credit divided into weeks? I've purchased 400 credits, not 200.
