Session Timed Out

When I started with TSX several months ago it was always “on”… I could walk away, leave the house, go to bed - & the charts were open & active when I returned.

In the last week or so, the platform is timing out & I have to log in again.

I watch 3 contracts & have 3 monitors each with their own browser/chart. When the session times out I have to reconfigure my charts again.

Is there, & if not there needs to be, the ability to not time out & stay logged in to our accounts/trading screens?
