All prototype interaction links disappeared after latest release update

Hello,

I have a big project with complex prototype (over 300 screens).  After the new release, my prototype mode does not show any connections in my file, only a starting screen. The desktop preview is working, but the share option does not have the link it is connected to. I am afraid that I have to redo the entire prototype. Any ideas how to fix this?

[Update]

Prototype connections not visible issue:

The connections are actually still present. I realised they appear when selecting a single artboard. This was a major change for me as I was used to seeing all the connections visible (in blue lines) when selecting the prototype mode... That is why the the preview on desktop was working - connections were there to begin with.

Lost shared link:

In the new version of XD the existing shared link is still absent.  I see only two options: Create New Link and Manage Links. This is still an issue if you are planning to update.

I reverted XD to previous version and the old link is back. 

PS: Removing prototype connections view for entire document (when no artboard is selected) was a big change that caused me a lot of frustration.
