Should I continue using the IMM eService App for my 90-day report or switch to the new website?

The user is currently using the IMM eService App for 90-day reporting, which has worked well for them, but they are uncertain about whether to switch to a new website that others are mentioning. Community members advise that the old system (the app) might be deactivated eventually, and since the two systems do not share data, it is safe to use both until the old one stops functioning.
