In my dictionary there is a word: ruuista, for which I cannot change the definition. The vocab is the Finnish one. I can change the definition and a fraction later it changes right back to its original definition.
My suspicion is, that the definition is shared with other people and some (temporary) lock stayed behind preventing the changed definition from being saved.
I know that Lingq has always claimed that the definition is private to me only, but I know for a fact that my definitions get changed by someone. For that reason I never use the definitions of others, because I know that if I change it, some else will change it too in some way. It may take some time, but it will happen.
Now this lock thing I have seen more often. I am just reluctant to report things because the Lingq team is not really respondent to problems being reported. Sometimes they get fixed, sometimes not. But feedback about that is non-existent.
It would be good to give feedback, not just “we will fix it” or “we will have a look”, but also what and when anything is going to happen or whether it will happen.
Please, let me know what you will do, and in this case I am curious about the cause.
