Android app unavailable

Links to install android app are broken and searching for the app on Google Play doesn’t show any results… what happened with the app?

The same thing happen to me! I tried to install Cospaces app from Google Play on my new Samsung S21 and I could’nt find it.
Anyone can help us?
Thankyou
