One click provisioning not working

[3lp4dr1n0]

I can't get the Azure resources deployed via the one click deployment button. Everytime I run the deployment, I get error messages around database account name:

ERROR DETAILS
The character 'A' at index 0 is not allowed in the DatabaseAccount name
ActivityId: 3300893c-050d-4213-9409-17afe8d43ef0, Microsoft.Azure.Documents.Common/2.14.0 (Code: BadRequest)

I tried already so many different names (different letters to start with, played around with the length of the name, etc...)

Hoping that someone can point me in the right direction.

Duplicate of #34 maybe? Can you try an all lower case name?
