@Rima, yes, please follow the advice provided by @pdram! But at the same time, please also be informed that there is a difference between the submissions and storage threshold the system offers. Submissions are interviews you submit to the server, which is 5k per month, while with storage, you can submit media files like images, video, audio, and files along with the submissions. This is limited to 1GB per account.
So, sometimes, deleting the project might also not work if you are over the submission threshold. You must either wait until the counter resets to zero for the next month or upgrade your account to exceed that threshold. However, deleting a project that consumed more than 1GB of storage would work to restore the storage counter to zero.
