Resmed Airsense 11 water tank not clicking solution

[JeffL]

I think I might have found a solution to the Resmed Airsense 11 water tank not clicking into place on the first try.

This morning I put a drop of baby oil on the vinyl connecting seal of both the tank and the removable inside connector. The tank easily slid into place and clicked on the first try. The last time I filled the tank it took 4 attempts before it clicked into place. This was the first time I tried this, but I'm optimistic that it will continue to work.
