What I did:I took meeting notes during a meeting in an iPad.
What happened: New text kept disappearing. Every few seconds the screen blinked pushing the curser to the bottom of the note (even if I made additional notes to the mid part of the document). After a while I started noticing that some of the text I had previously added at the bottom of the document disappeared. Gone. Poof. This is a highly dangerous behaviour.
What I expected: All text to remain in the document.
Things that might be helpful to know (Agenda version, OS and model, etc): Latest iOS.
At the same time my mac had the same not open on Agenda for the mac. It runs the latest MacOS. Possibly this caused some kind of sync loop where the MAc constantly overwrote the iPads newer notes. I force quit the iPad app and tried recreating the problem. It came back to the app on the ipad. Later I went to my desk and created a new note from the mac, keeping it open on the mac. Then going to the iPad to edit to see if I could reproduce the error. The note intially synced to the iPad but coult not be edited. The iPad app blinked like crazy and on its own (beats me how) created a new note instead of allowing me to edit the note created by the mac. I again force quit the Agenda app on the ipad and tried editing. This time it worked and the added text was properly synced back to the Mac without problems.
Reliability in retained notes IS KEY. This is the second time notes/text disappears for me. I thought the first time was a one-off. Now my trust in Agenda has been severly damaged. I will use Apple Notes instead until you report back that this has been fixed. It seems to be a bug in Agenda for iOS.
