I use multiple devices to write. When I walk I use Andorid. When I wake up I read and make notes on iPad. While working I use web / mac version. So it’s daily routine to me to add notes or edit the same node. Dynalist had SO MANY sync errors I can’t count them, so I just switched back to the workflowy + simplenote.
Don’t ask me to reproduce sync issues! Just edit same nodes from multiple devices, offline and then connect them to the wifi and see how some notes are overwritten. This was not good.
workflowy, simplenote and google docs always syncs nice after multiple offline edits. I dunno maybe you can ask Automattic for the fix ideas since they’re into open-source.
sync errors mostly happen after offline edits and simultaneous edits. Sometimes waitng for 15-30 seconds is needed to see errors appearing.
