No, you cannot on bankroll investments because your principal is included in your daily (gross) profit.
However you can stake your funds on Winza through the "HODL program" in order to divest anytime.
We have not faced any session issue so far, sessions last up to 24 hours. What is your current setup? Mobile?
how long does it take to divest from the normal bankroll? or are you saying principal gets stuck forever?
and i am on desktop trying from chrome, microsoft edge, and brave. all of them are logging out after 30 minutes of inactivity or so but it is only happening here
As I have said before there is two kind of investments: one is dedicated and it does not allow you to divest and the other one acting as a stake system allowing you to divest anytime. (actually because your money is always available in your balance)
This is really weird isolated case because we have not yet experienced such session issue, our technicians are already working on it trying to figure out what could be causing this problem to you. Can you in the meantime try another device as well as network in order to help us isolating the issue? Thanks in advance.
