This turned off my default, so there is no "leak" unless you opt into one.

Question I had connected my bluewallet to my own node but have not opened up the channel so funds get stuck then sent back now when using wondering how can I go back to default or what do I have to do to get default node settings back I could just dive further down and open the channel to move the funds??? hmmm

While this can be a concern Bluewallet is not actually leaking anything if you disable Groundcontrol inside the settings
