Hello, The service in the linked project does not have a volume?

Hi, as far as I can tell there is a line that says: the 512 mb are full. That is why I think that I cannot upload any data anymore. Is there a way to delete my old data?

There is simply no volume anywhere in this project.

Have you linked the wrong project? if so, please link the correct project.

Either way, since you are hobby now, you can grow the volume to 5GB from within the volume's settings.
