A number of LingQs for which I write a translation myself seem to disappear shortly after adding them, i.e. before I even close the lesson.
When I immediately check a given LingQ after adding it, it does exist. But after reviewing a few other LingQs, that given LingQ has now disappeared. Or the extra translation I had just added has disappeared (though in that case the already-existing ones remain).
Has this ever happened to you, or indeed to anyone here?
I would very much appreciate any insight into how I could fix this.
