Login on multiple devices since 4.1.16 update

[waccoe.com]

Hi. on our community every time a user logs in, it logs them out of all other devices. Meaning that when they switch device they have to log in again.

This only started after we updated to 4.1.16.

Can anyone let me know if something changed please?

I have this for a week or so: 

Already cleared cookies, etc. I have to login a dozen times in a day.
