Is there any limit on number of Listeners(subscription client) of a Subscription created under a topic in Azure Service Bus(pub-sub)?

Question

I am looking on using Azure Service Bus topic to publish some messages to my service. I have creted a subscription for my service and have got connection string. My service(WebApi) is running on large number of instances (1000s). I am thinking of starting the listeners of Azure Service Bus at app start of my service using connection string in all the instances. Are there any issues in running large number of listeners(my service instances) under one Azure Service Bus subscription. I am fine with only one instance receiving the message(This is infact what I prefer).
