The update will not handle this. I will speak from my own experience. When I updated, my apps were actually deleted and needed to be reinstalled. Whenever an app or apps need to be reinstalled you will have to reload the account/s. It usually offers for you to make a new account but not clicking it and simply clicking continue should get you finished up.
At first the accts may not appear because it can take a second or even a couple minutes to load. But your funds are safe.
Do not answer Dms they are not support and the users asking “did you fix your issue?” In DM, Are also suspicious in my opinion. Do not share your seed. Ledger will never ask for your seed and they will not DM you.
