Unable to create Sales Invoice from Sales Order (missing + button)

Hi all,
We seem to have a global issue where our “+” button has disappeared from the Sales Order dashboard next to “Sales Invoice.” This is happening for all users with all permissions levels. I am the system administrator and have all user roles. It used to be visible and was heavily used, and now we are missing it and I cannot find out why. Thank you in advance for your help!

May we know the version of ERPNext and whether this was noticed after an update?

I’m using the web hosted version, it looks like 12.14.0. I assume we are on the most up-to-date version of 12.0 right now? We haven’t switched to v13 yet. Thanks!

Please check if you have Accounts User role enabled for the logged in User?

These are all of the user roles I have enabled, and the permissions for Sales Invoice for these roles:

Thank you!
