Hi @abhijitna, If the TTL is not defined for the context variable of type UserSession or BotUserSession, the variable would last for 30 mins . If the TTL is set defined for the variable of these context types, the variable should be present for the specified time.
To test the same, I have created a UserSession variable with TTL as 200 mins (3 hrs and 20 mins). I have verified the context data for this variable after 3 hrs and 3hrs and 25 mins.
I see the variable in the context after 3 hrs and when I verified the context after 3 hr 25 mins, the variable is not longer available in the context because of TTL.
