I am going to a visit and I started updating fortnite but sometimes my internet crashes and the update stops...so I’d there any possible way to see the progress of the update??
Not unless you can see your own screen. I would suggest downloading Teamviewer on your phone and pc and then check in on your phone to see if your pc has finally finished the update.
See Teamviewer and download the free one for your pc and phone than link them with the code. and you can control your pc with your phone
