I have a student that cannot login to packet tracer after the Netacad migration.
They have uninstalled/reinstalled packet tracer, cleared all browser cookies, and removed any registry keys after uninstalling which seems to have no effect in resolving this.
When they login through the netacad login window, it just takes them to their netacad dashboard and doesn't log them into packet tracer.
They are also using the latest available version of Packet Tracer as of 2nd September 2024.
