Glad to hear that helped. The new 50 word limit is the default for all articles. If you want to have more control, you'd need to go to the Open Graph configuration area and create a new "Object". In the Object settings, you can choose a category to apply the settings to and in there, you can choose a meta description of 50 characters or 100 words or even a fixed description for every article in the category.
I hope that helps, but if you need more assistance with that, just let me know.
Thanks,
Alex
