When was LNMarkest removed from app store and why?
Looks like it was pulled from the store back in November 2025. The LN Markets team stopped maintaining their Umbrel app and actually asked for it to be removed themselves (Remove lnmarkets by vafanassieff · Pull Request #4057 · getumbrel/umbrel-apps · GitHub), so it got disabled in the store instead (Disable lnmarkets app by al-lac · Pull Request #4101 · getumbrel/umbrel-apps · GitHub).
You can still use LN Markets though, the app was mostly just a handy way to log in with your node. Just head to lnmarkets.com and connect with any Lightning wallet. If you want to keep using your Umbrel node’s funds, Zeus connected to your Lightning Node app works fine for depositing and withdrawing.
If you had an account set up through the old Umbrel app and need to get back into it or move funds out, ping LN Markets support. Someone else had the same situation and they sorted it out for them.
