Using Latest Japanese toilets

Am a bit embarrassed to ask this in a forum , but has anyone ever faced any issue using the Toto or any other latest toilets with sensors ?
I have a old one at home which works anytime as it doesn't have any sensor , but whenever I tried to use the latest one in public toilets it never works and I end up using the tissue papers , when I searched in the internet it said something about sensor won't sense if position is odd but I have tried different things and it didn't work out, anyone faced similar issue and solved it ?
