Hi Robert,
Unfortunately Coda’s phone app is quite limited and not so fast, so it’s far from ideal for note taking and capturing data on your phone.
On desktop with the help of some extensions it’s much better Powersave: Chrome Extension to save to any Coda table - Showcase - Coda Maker Community
Notifications should work though. I have no issue finding Coda in my notification settings.
Hope this helps,
Pablo
