Thanks for confirming, Sophie. It sounds like there’s a conflict with one of those two…I haven’t heard of any conflicts between them until now, but then this is the first I’ve heard of either plugin.
I wish I could offer up more on our end. Maybe contact the developers to see if they’re aware of anything to improve speed? If they wanted to reach out to me for a copy of the plugin (to test integration and improve for a future release) feel free to send them my way directly.
