When I tapped a section under offline state, it failed and a caution like above popped out (I don't use automatic translation at all as I've said in Prenvented publishing because of "unmodified machine-translated text", but it's not the matter this time.) The problem is, even after I came online, the section which said "Automatic translation failed" can't be edited anymore. Just saying the same caution. Is it possible to complete the translation in such situations?
