AE 2018 issue


I’m having a issue with the dynamic link between PP and AE 2018.

when I use PP and I want to edit a segment in AE so I would click on “Replace with after effects composition”. AE would start up and the video is there and working.

My issue is when I change something on PP the changes doesn’t translate over to AE for example if I change the colour grade on PP nothing happens on AE But when I change something on AE I see the changes over on PP. It worked before but I’m not sure why it doesn’t work now, I’m not sure if I accidentally pressed something wrong.

Granted I’m new to these programs and I wouldn’t be surprised if I pressed something wrong.

Thanks in advance
