I haven't had any issues with PolyFlex with the default profiles.
1. Make sure you are using a PTFE tube between the reel and the extruder, run through the filament guide.
2. Make sure you have a V2 extruder - it will be gray in color. If you don't have the version 2 extruder, you will need to upgrade it to use PolyFlex.
3. I usually purge with PLA before purging with PolyFlex since the PLA will be easier to push out of the print head during the purge.
4. Check that you don't have any blockage in the filament inlet. If you have strings from a previous material the PolyFlex won't be able to push it out.
If you continue to have issues, you may want to open a support ticket.
