Description David 2023-03-14 17:34:50 UTC 
SUMMARY
Discover hangs without telling me that it's doing something when I uninstall a flatpak app and let it delete the user data that came with it.

STEPS TO REPRODUCE
1. Launch discover.
2. Search for "inkscape".
3. Click the result for "inkscape".
4. Click Sources -> Flathub.
5. Click Install.
6. Launch Inkscape, do something with it, then exit.
7. Go back to discover, uninstall inkscape in the same window from where it was installed, and after that, click the button to delete settings and user data.

OBSERVED RESULT
Hangs for a while, then finishes and becomes responsive again.

EXPECTED RESULT
Should not hang. If it's doing something, should tell what exactly it is and show me a progress bar

ADDITIONAL INFORMATION
Comment 1 Nate Graham 2023-03-15 17:08:24 UTC 
Interesting. It's always been instant for me. I guess with a lot of data or a slower disk, it might not be. We should indeed make the I/O asynchronous and display a progress bar if it takes more than a fraction of a second.

flatpak: Improve feedback while removing user data

It seems it's really slow on some occasions.
