We have just migrated from 2012 to 2016 SSRS reports. So far it was no problems. However When testing the js script to go back to parent report when we opened reports in Chrome. We loose all the choices made at first. This works in IE but not in Chrome. And since IE is not supported after the summer we have been testing in Chrome and Edge and it dosen't work in either of them.
How can we get this function to work when we need to change the browser?
