We're having an issue where the nextLink with the skipToken is coming back and it is being used as-is for the next call. We get a random skipToken is invalid.
I've tested the url with Graph Explorer and it works. If I add extra characters at the end then I can induce the skipToken error. We haven't found anything on our servers that are adding characters.
Does the Graph API have an occasional issue with skipToken as of Jun 15, 2021?
Could it be something in transit that I haven't thought of?
