I was hoping to give your wallet a try with my c-lightning node. I'm not the most advanced user but am trying to learn. I installed the deb package first and it installed fine and opened to a completely blank window after crashing a few times. I decided to try the snap and got an installation error through the gui software center... then I tried installing through the command line and got this for output
error: cannot find signatures with metadata for snap
"Downloads/spark-wallet-0.3.1-linux-amd64.snap"
Maybe I'm just a little slow and missed something. Maybe somebody can help me or maybe my experience will help another.
