I tried again last week to do my 90 day online - usual problem, it didn't work - on either Chrome or Edge (or whatever MS is calling it now). Glad some people can! Not to mention some of the instructions are confusing. I managed once, about two years ago but never received a confirmation e-mail or notification other than it had been accepted for processing. Took a trip to CW and was told it had been received OK but I never received, nor could find, any record on line to copy for my passport. The IO said all was fine and printed me out a new copy.
