Why is Oreo so instable on Galaxy C5 pro

[Android Central Question]

Hi!
Since I've installed the update for Oreo, some of my apps like Gmail, Agenda, or my bank online app don't run anymore and no easy way to downgrade.
What about you?
What's your advice for me.

Thank you.

Welcome to Android Central! What do you mean they don't run any more? Do you get an error message?
