My son's rating opened when he played international match during August 2023. The rating was displayed in FIDE website on the last date of August, and it was 1156.
Later on September he played another international tournament and there was no change in rating. That was also displayed in FIDE website on last date of September as 1156.
It was the same till October 7th and suddenly on 8th October his rating is displayed as 1031 in the FIDE website. Do anyone can help to fix this issue?
