Hi I asked about 90 day online reporting a little while ago. Well I want to do it today as I’m within my 14 days before my 90 days are up. I’ve always done it by post up until now. Just a few question about the process.

1. Can you use an smartphone (iPhone in my case) to do this 90 day online reporting

2. Can it be done any time of the day (evening)

3. Any top tips for things or other advice or pitfalls about this process.
