Ripple tool cannot freely move

Hi @alext95761221 -
Thanks for the report.  Do you have Transmit enabled and set to an external monitor in Prefs>Playback and is "Composite Preview During Trim" enabled in the timeline wrench menu? If so, there is a bug in Beta if you're on macOS that is now fixed as of Premiere Pro (Beta) 26.1.0 x004.  Thanks!
