I haven't because I use VPN once a while and once the purpose of me using it ends, then it becomes of no use for me then to exit it and disconnect, but before doing that, I ensure closing the tabs opened and websites am using the VPN for, if I don't do that before switching off the VPN, the IP address will change and it will rang an alarm on security bridge on their network if am visiting from a restricted region or so, that's why we need to read very well the terms and conditions of a platform before using them, some allows and done do not allow for the use of VPN.
