I logged into Dynalist this morning with the express purpose of testing this, so that I could give you the clearest feedback possible.
It seems that there is no reliable way to reproduce the problem, but it will occur at some point in an extended use session. The change in zoom level can be triggered by:
- Switching to another app and back again (swipe/app switcher/tab switcher).
- Switching to another Safari tab and back again.
- Switching to a different Dynalist file.
It happens in portrait and landscape, with touch or with keyboard/trackpad.
When Dynalist is affected, other non-Dynalist tabs are not (including this one, the forum, or the Dynalist log-in page). I have tested this with many tabs open.
I usually view Dynalist at 75% or 85% (using the AA button in Safari’s address bar) as the default is too big. It’s possible that this is the root of the problem, but it’s the only way to make Dynalist useful on an 11” screen. I have been unable to replicate the problem when using Dynalist at 100% on a fresh load.
Maybe the answer is just to make the default view smaller. 85% is comfortable, but 75% is probably even better.
I hope this information helps you to narrow the problem down. I’m all-in on both Dynalist and iPad, so having the two work together seamlessly would be incredibly useful…
