Comment 1 Aleix Pol 2021-04-30 01:37:50 UTC 
I can reproduce it for applications I already have installed. Can you confirm that you have the same problem?
Comment 2 Felipe Kinoshita 2021-04-30 02:28:05 UTC 
Yes, this only occurs with already installed flatpaks.

flatpak: Use async API to search for already installed flatpakrefs

libflatpak will refuse to give us a ref if it's already installed, so we
want to rely on the installed db. At startup it might not be loaded yet,
so let's just call a function that will do the right thing at the right
time.
