Hello,
we are using LS Version 2.06+ Build 160129.
After latest update (we suppose), when a user stays on a survey page for too long (like 60 seconds) he gets a "Session Expired" message.
I looked on the internet and all the solutions provided were useless.
How can i troubleshoot this?

Thanks,

It looks like it happens on a single survey. Any clues?

Correction: it happens on any survey and the timeout happens after about 2 mins.
