LearnPress breaks Flamingo plugin

I’ve just updated all my plugins, including Flamingo (now 1.8) and LearnPress (now 3.0.0).

It seems that when the LearnPress plugin is activated, that the Inbound Messages list is empty in Flamingo. So there’s some kind of conflict between the plugins going on.

When this issue is occurring, the counts of the messages are shown in the dropdowns, it’s just that the main list of messages is always empty.

Here’s a screenshot: https://i.imgur.com/D85ZxRB.png

I’m not seeing any errors in the PHP/Apache error log.

Flamingo is a very popular plugin (10x more installations than LearnPress) so it would be good if this conflict were resolved somehow please. I’ve needed to remove LearnPress from my client’s website until the conflict is fixed.
