I'm wondering if MS has figured out a way for a user to manage ALL of their Alerts across all sites/sub-sites without having to go into each site to do so.
I don't understand why in 'almost' 2019 this can't be done easily yet. If there's something within the system that I just can't find, please let me know. Thank you so much.

I am afraid there is no way to manage all alerts across all sites by OOB method in SharePoint online.

Then we can manage the alerts by PowerShell in SharePoint online.
