I'm using Studio 2019 and clicked the little bell at the top right this evening, to download and install the latest update - unfortunately I didn't note the number. After giving the go-ahead to install the update, Studio 2019 appears to have vanished from my laptop - it's not listed on my applications anymore, the short cut has vanished from my task bar. I went into my SDL account and tried to re-download my upgrade from 2017 to 2019, but that wouldn't install because it could detect a later version. I then tried to uninstall 2019 in the control panel, but that wouldn't work either. Does anyone have any ideas or has anyone else had this issue with the update?
