Describe the bug / error

I have a custom search solution that uses search suggestions api:

/_api/search/suggest?querytext='tes'&inumberofquerysuggestions=10&fprequerysuggestions=true&fprefixmatchallterms=true&culture=1033

This api endpoint used to work before but has started returning empty results lately.

I also checked on other tenants as well, the api doesn't return results on all tenants (it used to return results before).

I have a query suggestions text file in place as explained here

Steps to reproduce

1. Login to any SharePoint online tenant
2. Add a query suggestions text document like the one attached by following steps mentioned here
3. Try to query the suggestions after waiting for at least 24 hours
4. Test the api endpoint after 24 hours of waiting: /_api/search/suggest?querytext='tes'&inumberofquerysuggestions=10&fprequerysuggestions=true&fprefixmatchallterms=true&culture=1033 QuerySuggestions_alwayssuggest.TXT

Expected behavior

If the query suggestions have been added, the suggestions api should return suggestions for any text that belongs in the suggestions text file

I am seeing this as well in my environments.
