For push notifications, we recommend #SunUp. The #Holos beta-14 version fixes an issue we had with the #UnifiedPush library. Remember to re-register if you're not receiving push notifications.

#Fedilab uses #UnifiedPush for push notifications in every version. The Google Play version comes with a built-in distributor that relies on Google, so notifications work right away. The #FDroid version cannot include that built-in distributor, so you need to install a separate one, like #ntfy or #Sunup. Once it is installed and selected in Fedilab, push works the same way. This is why F-Droid users need an extra app while Google Play users do not. This extra step is not specific to Fedilab.

I would like to thank you all for respecting my choice to leave the Google Store. Seeing messages from people joining #FDroid to get the app and sharing their experience with a lot of good feedback made me very happy. What I read most often: F-Droid is easy to use, and the export/import feature works well with #Fedilab.
For push notifications, I recommend using #SunUp
