Free tier usage limits effective 1 April 2020

### Please see important update: [Free tier usage limits now effective 1 May 2020](https://github.com/Azure/AppConfiguration-Announcements/issues/9)

Configuration stores created during the public preview period have been automatically migrated to the Free tier. Stores in the Free tier are limited to 1,000 requests per day. Currently, we are waiving the daily request limit for Free tier stores created during the public preview period.

Beginning 1 April 2020, we will enforce the daily request limit for all Free tier stores, including those created during the public preview period.

If you used App Configuration while it was in public preview, we recommend that you review the Total Request Count graph on the Overview page in the Azure portal to understand the number of daily requests made to each of your configuration stores. Consider upgrading to the Standard tier for any stores receiving more than 1,000 requests in a single day. You can upgrade from the "Scale up" tab in the portal.
