That's another well documented annoyance. The VM SH2 Trial Forum had pages of threads on the subject. The phenomenon has abated (not gone away) with v26 firmware.

I was told by one of the actual firmware bods that it was down to the implementation of stringent VM's security requirements and was a timing decision in the firmware.

As I said, it's abated due to firmware changes. But I still get it occasionally in other places, for example being sent back to the login screen if I try to change router/modem mode. I can try several times (sometimes) before the change I want has been actioned.
