Well if the first line timestamp is not old, then it implies syncthing was not running.
There are options to make it run in the background in settings.
I seem to remember a similar issue about funny business happening when pictures are saved from camera - however I can’t find a discussion in the forum or issue tracker. Maybe @Nutomic remembers (or I simply misremember)?
In the experimental options, you should activate the run with foreground priority or the keep cpu awake option.
There was a discussion, where taking screenshots would touch the file twice until all data was in it, but only the first one was synced immediately and the second one (on my phone) a minute or so later).
I have the same issue with screenshots on my Nougat device. For me the solution is launching Syncthing app manually (without running in background) when I need to sync stuffs with my PC.
