Inconsistent Sprints Integration with Desk

Hi,

we are using Desk and Sprints.
Naturally, we are using Sprints for Desk for quite a while.

Today I've got an email from the Marketplace :

Interestingly, I got the email today Feb 23, telling me that my installed extension will stop working on Feb 21 ... two days ago.
Doublechecked: Sprints is still running in Desk...

I wanted to update this, went to the Desk Marketplace and Sprints for Desk is gone...

Expilicitly searched for it, its still there.

Did anyone test the process on your side?

Only the new version 15 is available, so I decided to install it.

As a result, I have two versions of "Sprints for Desk".

I found a help document that tells 'all linked sprints tasks will be unlinked' as soon I remove 'Sprints for Desk' from my extension list. Now I'm afraid to delete either one of the 'Sprints for Desks' Extension instances.

I am again confused and finding your bugs is very time-consuming and frustrating.
