PVA filament breaks inside the MMU

I recently got a newly upgraded i3 MK3S + MMU2S working and have done a few single-material PLA prints with each of the material slots and everything seems to be working quite well. Unfortunately, I'm having an issue when I try to print soluable supports. I bought a spool of PVA to use for the supports but almost every time the MMU unloads the PVA to switch it out, the filament breaks off in the MMU (leaving some filament inside the feed tube) so it can't finish unloading it and the print fails. I tried several times and never got past the third layer due to this issue.
Does anyone have some advice for working with PVA with the MMU2S?

Some people said that it is working well by using the BVOH profile. Myself I could not make it work, I gave up.
