While using the Hebrew Wikipedia android app (on Flyme OS 4.5) and clicking on the "edit" button of a section, the editing text shown is not of the selected section, but of the previous section (for example, clicking on the "שכווי" section editing button here causes an opening of the "שבט המסאי" code for edit.
This might be a problem of the multilingual app. However, as a Hebrew speaker, I did not use the English app, so it might also be a local problem of the Hebrew translation.
