Our business area has been telling us weekly that some users are experiencing problems:

• When opening a second OTM tab in the browser → Error or session expired appears
  • Either from the Home menu, by right-clicking and 'Open New Window'
  • Or by accessing it from the main URL again, but a second time and from a second tab (two active sessions in the browser)
