Momcozy Pump … Ouch

Finally got a wearable and love it, aside from how rough it is on my nipples that is. I got the Momcozy M5, and it is good at emptying me but feels like my nipples are being pinched the entire time.

I can’t handle beyond level 2 on the Momcozy generally but can easily go much higher suction on the Spectra s1.

Anyone else have this issue with this pump, or any other wearable (Momcozy or other)?

I don’t want to give up on this wearable as it has made life a lot easier when home alone with a fussy newborn. Any tips? I have tried a smaller flange (19mm like I use with the spectra) and slightly larger (21mm) but hurts either way.

EDIT: Tried the coconut oil and does feel a bit better! Managed to get to mixed mode level 3.
