Embedding part of Excel file from Onedrive in iframe stopped working

MartijnStaphorsius I have a very similar problem and would be interested in a solution! I called MS support but they couldn't help me. After the problem as Martijn writes, I tried to generate the iframe code again, but the address in the code is no longer "onedrive.com" but "1drv.ms" and the link does generate, but I can't work with the file as if it was in read-only mode. For a few months everything worked without problems (excel where on my website it was possible to configure via menu the exact specification of the product), but since last week it is impossible to work with the table in the iframe. Anyone have any idea where the problem might be?
