Outlook 365 calendar events no longer show up on my Outlook iPhone app

See thread title. All the information I’ve found about making the app calendar sync up involve adding my Outlook address to Mail settings on the iPhone, but I don’t want to do that–I’d prefer to use “mail” for my personal Gmail and use the Outlook app for business related mail. Plus, my calendar events USED to show up in the phone app; they just stopped a few days ago.

Help please!

Answering my own question–I deleted the app and re-installed it. Calendar events now showing up. Kind of annoying to have to do it, but it worked.
