Getting "Something went wrong while generating a shareable link for your collection"

My question:
Getting “Something went wrong while generating a shareable link for your collection. Please try after sometime”, each time I tried to create a shareable link using Via Json link.

I have already tried updating the App version and restarted the App, but it didn’t helped.
When I click on Share >> Get Link for particular collection, it will show “Fetching Link” .
but nothing happens after that. We can not see link generated for this collection.

pls help me to sort out this, as I need collection link, in order to run the APIs in Newman.
