Pretty sure it’s on there from memory, try connecting to the community App Store instead of the official start9 supported one. I could be wrong 😑
Yes but you can only activating developer mode

Thank you very much. Will take a read later
Yep! It is. Now when I see it, it says that it is already installed (that being bitcoin core). So how to switch between the two, and what does this do exactly for when one sends a btc transaction to a sparrow wallet using electrum server?
