Why are older connect jsons being polled?

Hi,

We just released a new version of our Add On (3.0) a week or so back.

Now, we were expecting that Atlassian will stop polling the connect json of our older 2.0.6 version. However, we instead see that it is continuing to get polled. We know this because we get “Error polling your descriptor” error emails.

Can you tell us why? Our new 3.0 version is supposed to auto upgrade all our client installations automatically. So, we are expecting the polling should stop?

Thanks
