Issues to apply severity and priority for Create

Hi @nick.thomas,

Here is a list of bugs without severity and priority for the team.

We would like to ask you to:

Work with your team to triage and add a severity label (~S1 / ~S2 / ~S3 / ~S4) and a priority label (~P1 / ~P2 / ~P3 / ~P4) to the issues in this list.

The definition of these labels are defined at:

• Priority Labels
• Severity Labels

For the issues triaged please check off the box in front of the given issue.

Please work with your team to complete the list this week.
