Just got caught out in losing a load of changes in our dashboard.
For example I alter our VLAN scheme on our MX. I click Update and I'm returned to the Addressing and VLAN page. The dialogue for the page says "You have unsaved changes" > I click Save The page updates and the dialogue reappears.
I cannot make changes to my addressing and VLANS.
It seems to be just this page. I've enabled third party cookies - I've switched off anything ad or script blocking. I've tried in: Firefox, Edge and Chrome.
