I have a youtube data API v3 project setup with
key: AIzaSyDZbBDtj8FPS-XbiI7frFXiylBpeBXXXXX
Currently daily quota limit is not displaying any value and still able to request and get data from Youtube Data Api v3. Since this is a development server key wherein on production server we were previously having daily quota limit of 300 000 (On and before Jan2020) but suddenly seeing the only 250 000 without prior intimation.
May I know what causes that limit getting decreasing/increasing in either of case.
