I bought this Foodsaver yesterday.  I used my previous foodsaver frequently to vacuum seal jars.  Today I tried using it to seal jars.  The foodsaver accessory hose does not fit into the accessory port!  It sits partially into the the accessory port but does not snug into it.  The hose falls off and there is no suction.  We tried and tried, watched videos, and studied the manual, and checked the website.The port will not fit the accessory hose that is show to use with it. We are so upset!
