First, I can access computers remotely from my iPhone running iOS 12.1.2. The problem is using a web browser. I log into Access, click on the computer I want to access, a new tab comes up- all as usual- but that tab stays white. No desktop of the remote computer appears. Of the two computer I've tried to access, one is a MacBook running High Sierra, the other is an iMac with Mojave. I'm running Mojave on this iMac as well. I've tried removing the "fix" of removing the Parallels Access Agent app from the Accessibility page in settings and restarting- twice...it has not worked. Anyone have any ideas? Is the same thing happening to anyone else?
