Cancel a Trade for Waivers or wait?

I sent a trade (Crowder and Landry for Chubb) and wanted to get it done before the waivers ran so I’d be able to use some FAAB on waiver choices. The guy I’m trading with has gone radio silent the last few hours about finalizing it so it can be pushed through. Should I go ahead and leave the trade out there or cancel it and go through my waivers as normal. I don’t have to pick anyone up but who the show today hard sold me on Justin Jefferson. What Should I do?
