software.insert.io repository no longer exists
We've been using Pendo 2.1 in our Android app for some time now, using the repository at https://software.insert.io. Just yesterday I went to make a new build and was surprised to find there's no longer a repository on the other end of https://software.insert.io.
Pendo's documentation for 2.1 still lists this as the repository location so I'm at a loss as to how to continue using 2.1. Is this version no longer to be used and the expectation is that we must upgrade?
Thanks for any help you can offer here.
