No the token timeout is set to 1hr. We've had 403's forever to be honest. They happen when the site has been sitting and I click on another tab in a report. Time is 3-7 minutes, but not always. Sometimes longer...but seldom a non-issue. We have 4 embedded reports up behind our paywall. The tabbed ones are the main issue. There are lots of filters and data...and the app is really useful and fast. Very good market reception. Can't say I recall a non-tabbed one giving me trouble but I'll look more carefully going forward. Now that we're live and have users starting up...we're paying more attention in general. Tom
