What problems is Azure App Service solving and how is that benefiting you?
CDN is the future totally ecologic. Web app + GitHub, domains is bit expansive pricing. Web app + Sql is cool combo, could you have more like that.
About create new IA scale plan:
I know that you have capacity to do it, and only you have it..
It could have its own scale intelligence option, where it commands and use cpu increase performance when need with help IA, same to increases memory as needed, add extra configs costs when marks add's like sql, functions, domains, etc. also a monitor of active costs and limits maybe with a pre-deposit balance
About support:
I believe that in most cases, the first reply support response usually solves it, well, why not create a support ticket that only returns one response solution; It would also have to end up with duplicate tickets. Maintaining quality support for all users and maybe paying to open more than one or many tickets. Review collected by and hosted on G2.com.
