Hi, the new metadata file on Weblate is somewhat borked (at least for Icelandic); yesterday it was fine with 15 new strings to translate. This morning (GMT) I got announcements that there were new strings: now there are many empty strings and most of the already translated strings have emptied the original English field. See https://hosted.weblate.org/projects/f-droid/f-droid-metadata/is/
Please look into this.
BTW: Yesterday in another project (separate Weblate instance at https://weblate.securedrop.org/projects/securedrop/) there were problems with similar symptoms in some languages due to an upgrade, perhaps it’s related?
