Note: this might be similar to another issue with 7.x here - https://www.drupal.org/node/2751831#comment-11466387 → - but I'm getting it with 8.x-dev.
I'm using Mailchimp 8.x-dev, Drupal 8.1.8.
On localhost (homestead setup with php7/nginx) mailchimp lists work great.
However, on a fresh DigitalOcean install (Ubuntu16,PHP7.0,Nginx, SSL) whenever i run a cache rebuild, i loose all the lists in mailchimp - and the signup forms stop working.
I get the following notice when going back to mailchimp and clicking to refresh the lists.
Notice: Trying to get property of non-object in mailchimp_get_lists()
I'm having a hard time finding rhyme or reason for it. When it stops working, it doesn't work immediately after drush cache-rebuild, cron run, etc. Then in an hour or two, or sometimes the next day, it'll just start working.
