Sorry to repost the following but does anyone else have any ideas?
I exchanged DAI to ETH within my xDai/Burner thing, and it's all gone. It went out successfully but didn't ever come back in as far as the Burner's concerned.
My Etherscan still currently shows the $25 of ETH that I expected to have:
However I can't see or exchange a thing within my Burner - the Burner wallet is definitely the same as listed above. The developer of Burner mentioned a possible problem with "my connection to Infura" and asked if I was using MetaMask but I literally don't have a clue what these things are unfortunately :(
