Why does the link between the table and the form stop working?

Question

Google Sheets

Good afternoon. For some reason, the links between the Google form and the table into which the answers are uploaded stopped working. Attempts to rebind only return the first row (column headings aka question names on the form). Linking to another table (as well as creating a new one) works great, but that particular table is needed. How would you get it all back? The changelog does not show anything that could help.

Answer 1

As a result, it turned out that periodically uploading answers exceeds the maximum allowable number of cells in the table (2 million). And no, this is not much, because the Googlesheet counts ALL the cells GENERALLY (a conversation with their technical support helped).
