Not sure if it's an Aurora issue or a Lava issue.

Oh, I didn't know it was on Githlb.
What's Lava's Github account? It's not linked on their site.
Oh sorry not sure for that app. It should be if it’s open source…
Oh, all good. I thought you meant for this app specifically. I normally use FDroid for my apps, or Obtanium if I need to. I only go to Aurora as a last resort.
I'm not sure the Lava app is opensource. nostr:nprofile1qqs2wn8h6dw8snma59c93yzuan0tjhwk67vf7w9erj43cxwpx7umstspzamhxue69uhhyetvv9ujumn0wd68ytnzv9hxgtc5z8234 when your app in FDroid?
