I'm not happy either, basically they abandoned development of WiFi sync and I think it is because they could make a little money doing cloud sync instead so they tried to make it better. Sure it's low cost in some people's perspective but I do not do cloud sync because of my security needs in certain areas of my task data. I protect as much of my networks as I want, yet MLO does not give me any choice to protect data unless I can keep that data only in my own network.
I knew it was trouble when it only asked in configuration which one I want to overwrite in a conflict. Um how about show me both to choose or edit?? It only works for me if I always remember to sync before I make any edit on either my PC or Android, and then remember to sync again after I often edit on PC then rush off with the phone so it needs to be on there. A task manager should never become the project, but making everything correct in MLO is the biggest project I've ever experienced (having done software programming for decades).
There are tasks that I complete on the mobile version and others on the PC. In the synchronization settings, you can choose Local or Remote in case of conflicts. But let's say I created a to-do list on the PC and changed it on the smartphone. If I selected the Remote option, I will lose local changes. And vice versa.
