Unable to create Azure App Service plan in US East region with error "This region has quota of 0 instances for your subscription"

Question

I'm trying to create a new App Service plan (using the P0V3 SKU) in US East region, and I continually get the following error message:

This region has quota of 0 instances for your subscription. Try selecting different region or SKU. (Code: SubscriptionIsOverQuotaForSku)

If I change the region to US East 2, then I am able to create the plan.

I've done a bit of digging, and while I haven't found anything official, I have seen comments from folks at MS that there are hard regional limits on certain resources. See the answer to this question for an example: https://learn.microsoft.com/en-us/answers/questions/878011/cant-create-function-app-get-this-region-has-quota?source=docs

Is there anything I can do to resolve this issue? Can I reach out to someone at MS that can allow us to create resources in the US East region?

Our team is in the process of migrating our entire cloud infrastructure to Azure, and all of the infrastructure we currently have is in the US East region. Some of our app service instances will not be publicly accessible, so having them in a separate region would either require us to move all of our infrastructure to a different region, or to pay a significant amount more in monthly costs to connect private resources across multiple regions. Neither of these options are great. Even if we move everything to a different region (i.e. US East 2), wouldn't it be possible for the same quota/limit issue to occur in that region as well?

Thanks!
