Hello,
We're checking the Sec-Ch-Ua coming from MS Teams to determine if the request is coming from MS Teams. We noticed that this header is not always sent depending on the version of MS Teams:
- 24295.606.3238.6194 -> header is not present
- 25010.201.3348.6919 -> header is present
Was there an issue with this header in prior versions?
Thanks!
