What I did: Went to On The Agenda view to edit notes on my iPhone.
What happened: App rapidly cycling through old notes for several seconds up to a minute or so. Some of these notes are up to 4 years old. After stopping, the cycling starts again if I try to manipulate a current note. Unusable. Occurring only on iOS. Not macOS. Not occurring in Today or Todo views. Scrolling choppy across all views.
What I expected: Function that I previously experienced.
Things that might be helpful to know (Agenda version, OS and model, etc): Agenda 22.0.2, iOS 26.2.1 on iPhone 16 pro max.
I tried this advice and it worked on Mac and iPads, but the iphone keeps endlessly indexing in the On The Agenda view, no matter how long I let it run on other projects. I uninstalled and reinstalled Agenda on iphone without luck. Hoping that new updates on Agenda and iOS 26.3 might help something. Just keeps endlessly cycling notes in On the Agenda view.
When you uninstall, it has to start the whole process again.
Here is what you could try:
Usually, this is simply a case of giving the device enough time to catch up. You could hold Agenda in the foreground for a while, just stopping your device from going to sleep, to give it time. Select a project with not much data, not On-the-Agenda. If you don’t want to to have to constantly keep the device from “sleeping”, you can turn off the Autolock in the Settings.
Just let it work on it for an hour or so. With any luck, it will finish, and be done.
