Did you know that there is a max character limit of 4,000 characters when leaving a review on a business or organization within the Google Maps local pages?
Jade Wang posted in the Google Business Help forums that sometimes when your reviews are not process, it can be because of that character limit.

@Juliette, I think you may be hitting a character limit for reviews (~4000 characters). I know you spent a long time on the review, but is there a way you could try to cut it shorter and see if it will post?
So even if you had a lot of good or bad things to stay, you need to keep it under 4,000 characters.
