Hi, guys! I have the same problem, noticed yesterday. In activity tab last information was for 1 Feb.2020 but I have received coins few days ago. My balance was 1.5 btc but now shows 0!  I trying to recover seed phrase to electrum and it passed and wallet has synchronised but it is the same thing - last transaction shows for 1 Feb. 2020 and no money on balance. Any suggestions?
