Media Insights Deployment Fails: Specified ReservedConcurrentExecutions for function decreases account's UnreservedConcurrentExecution below its minimum value of [10]

Question

I am currently trying to deploy Media Insights via CloudFormation and this template: https://solutions-reference.s3.amazonaws.com/media-insights-on-aws/latest/media-insights-on-aws-stack.template

The install continues to fail when configuring Lambda with the following error: Resource handler returned message: "Specified ReservedConcurrentExecutions for function decreases account's UnreservedConcurrentExecution below its minimum value of [10]. (Service: Lambda, Status Code: 400, Request ID: afb4680c-12d1-4f13-b900-e0eadcf49590)" (RequestToken: ef544d25-c560-5c31-3ee5-a514998d485f, HandlerErrorCode: InvalidRequest)

I have requested to increase concurrent executions on my account. However, it seems that may take some time. Does anyone else have any other recommendations to work around this problem?

Thank you!

A countermeasure would be to set the "ReservedConcurrentExecutions" parameter of the Lambda function to less than the number of concurrent executions for the account.  
Removing unnecessary Lambdas that are set to run concurrently in your region may also be a solution.  
The best thing to do is still to make a request for larger quarters as you have done.
