Hey Geoff,
Thanks for the response.
I tried reverting back to the twenty-fifteen theme, and was not able to get the snippet to work. Is it possible that there is a more direct way to affect the limit of the plugin? I realize modifying the plugin code directly is not ideal, and will potentially conflict with future updates, but I would be willing to do that if it solves my problem in the short term.
Thanks again for all your help, it’s much appreciated.
