question

Actually, I see the issue. The issue is the same as yesterday (it's specific to titles using gzip headers on requests), but only in the "low" vertical, which your title is in (due to being an Essentials tier title which is sending an excessive number of API calls). The low vertical is a quarantine space for Essentials and Indie tier titles which are exceeding our Fair Use Limits, so that they cannot impact other titles. It looks like the change from yesterday is now being added to that vertical, which will resolve the issue for you - apologies for the delay, but we do have to concentrate our work on our shared service and Pro/Enterprise verticals first, as those service segments have titles with Service Level Agreements which we're contractually required to meet.

We'll have a write-up of best practices for call rates on the site shortly, but in the meantime, this post contains a good write-up of the way to think about your requirements and how you should be approaching the implementation: https://community.playfab.com/questions/12094/data-heavy-games-and-rate-limits.html.
