Hello David, Great tutorial! I was wondering whether you have come across the "Invalid Signature" error while creating bucket in studio? I have tried both, S3 Mimio storage and default volume storage. Both result in the same error. Common fix suggestions refer to default ANON_KEY and SERVICE_KEY mismatching, however, in your tutorial you have guided how to update them, so presumably they shouldn't be an issue, however, I get exact same error every time I'm trying to create a bucket :/ Thanks for your tutorials, they're great!
