Progresso 18.3 and Google account

[Ditto]

If you are a GSuite for Education and progresso user, you may find when you go to http://www.progresso.net, if you are logged in to your google account it will auto login. Personally, I find this a slightly dubious approach even where I decide to use my Google account to authenticate. However, what I am really not happy about is if I click the sign-out, it logs me out momentarily and then immediately auto-signs me in again. The only way to log out of progresso is to log out of your google account. I raised this with them yesterday but clearly. Support first said the product teamed said this was not a security issue. Next, they decided to say this was the case in the earlier release. It was not, the earlier release did often auto log you in, but if you signed out from the home page, you got logged out. If you are also unhappy with the behaviour in 18.3, could I ask you to log a case with support.
