telegram desktop doesn't remember settings

Tried installing telegram desktop from ubuntu software, (uninstall) then synaptics package manager (same issue)

Login with phone number and enter access code. Works for 5 minutes, then when switch back from other application, met with original install "Get Started" screen.
