correcting app insights daily cap details

Application Insights ingestion service now enforces daily cap correctly. For telemetry that targets classic components no changes are required, however for customers using workspace-based components they must review daily cap settings on BOTH App Insights and the backend LA Workspace. Also, adding note about how regional and global endpoints may have different behavior and App Insights daily cap is regional but LA daily cap is global. Its a mess, but hope these changes clear it up for customers.

 When data collection stops, you effectively have no monitoring of features and resources relying on that workspace. Instead of relying on the daily cap alone, you can [create an alert rule](#alert-when-daily-cap-is-reached) to notify you when data collection reaches some level before the daily cap. Notification allows you to address any increases before data collection shuts down, or even to temporarily disable collection for less critical resources.
 
 ## Application Insights
-You shouldn't create a daily cap for workspace-based Application Insights resources but instead create a daily cap for their workspace. You do need to create a separate daily cap for any classic Application Insights resources since their data doesn't reside in a Log Analytics workspace. 
+You should configure the daily cap setting for both Application Insights and Log Analytics to limit the amount of telemetry data ingested by your service. For workspace-based Application Insights resources, the effective daily cap is the minimum of the two settings. For classic Application Insights resources, only the Application Insights daily cap applies since their data doesn’t reside in a Log Analytics workspace. 
 
 > [!TIP]
 > If you're concerned about the amount of billable data collected by Application Insights, you should configure [sampling](../app/sampling.md) to tune its data volume to the level you want. Use the daily cap as a safety method in case your application unexpectedly begins to send much higher volumes of telemetry.
 
 The maximum cap for an Application Insights classic resource is 1,000 GB/day unless you request a higher maximum for a high-traffic application. When you create a resource in the Azure portal, the daily cap is set to 100 GB/day. When you create a resource in Visual Studio, the default is small (only 32.3 MB/day). The daily cap default is set to facilitate testing. It's intended that the user will raise the daily cap before deploying the app into production. 
 
-We've removed the restriction on some subscription types that have credit that couldn't be used for Application Insights. Previously, if the subscription has a spending limit, the daily cap dialog has instructions to remove the spending limit and enable the daily cap to be raised beyond 32.3 MB/day.
+> [!NOTE]
+> If you are using connection strings to send data to Application Insights using [regional ingestion endpoints](../app/ip-addresses.md#outgoing-ports), then the Application Insights and Log Analytics daily cap settings are effective per region. If you are using only instrumentation key (ikey) to send data to Application Insights using the [global ingestion endpoint](../app/ip-addresses.md#outgoing-ports), then the Application Insights daily cap setting may not be effective across regions, but the Log Analytics daily cap setting will still apply.

 ## Determine your daily cap
 To help you determine an appropriate  daily cap for your workspace, see [Azure Monitor cost and usage](../usage-estimated-costs.md) to understand your data ingestion trends. You can also review [Analyze usage in Log Analytics workspace](analyze-usage.md) which provides methods to analyze your workspace usage in more detail.
