Thank you for this - yes you’re right, this is a hard lesson and luckily the stakes are fairly low for me. Had my startup been bigger though there would be pain and panic.
Thank you for pointing me toward the azure 3.5 - I will definitely check that out and that is the kind of solution I am looking for.
I’ve now signed up for an Azure endpoint - let’s see if it gets approved. It looks like the process to get a key is going to be a bit of a PITA.
