Translation of the most relevant segment of the announcement, using Google Translate:
"After the unprecedented decision of the municipality of Plovdiv to violate the preliminary agreement for the use of the Hristo Botev stadium and to refuse the Bulgarian national team to hold its next match of the European qualifiers at the facility, and subsequent communication between all interested parties, including . state authorities, today UEFA ordered that the match between Bulgaria and Hungary be played at the Vasil Levski National Stadium in Sofia on 16.11.2023 at 7:00 p.m. behind closed doors"
For more information regarding the situation and what led up to it out, you can check out this post from yesterday, which I try to update with the latest information:
