Magento reindexing no longer working

I have had the search working well for a few months on Magento. Today the reindexing stopped working.
Usually reindexing the “Algolia Search Products” is not a problem, it is set to manual and takes 10-20 seconds.
Now I am getting errors when reindexing and in the Magento “exception.log” I can see:
“Exception message: objects cannot fetch more than 1000 hits.”

Search on the front end is still working but I am worried the results and prices may be getting out of date etc.

Is there any other support channel for Algolia?
Do Algolia have a support email address I could try?

Hello @scott,

there was an issue with 1000 products limit in older versions of the extension.
Could you upgrade to the latest one?
