I cannot update right now, I will need to update a lot of themes, plugins and mu-plugins codes before deploy to production the latest WordPress. I still using the version from Debian (Stretch), planning to update to Buster (WP 4.9.5) or native WordPress 5.4.2, but I do not have time, because 2 projects needs to be integrated to the platform and them need “non-google” forms and CSV list export option. The plugin is great, but for we It need to work on 4.7.5 for now, even with a workaround.
