My first ever online 90 day report I ever did was believe it or not in November 2014 having a work permit and non-b visa.
It was a ball ache back then to get it working. However, In 10 years I only had to go to report in person once (including throughout Covid) because they were upgrading the system at that time.
I understand the guys question about browser because it used to only work on internet explorer for me and not chrome for example. But those days are long gone.
