new Azure Spatial Anchors 2.7.0 SDK fails to upload cloud anchor in iOS 14.2

I've been using the old 2.2.1 SDK for a while until yesterday when I updated my iPhone 11 Pro to iOS 14.2 and upgraded to 2.7.0 SDK. Calling Cloud Anchor Upload sometimes works, other times it just timeout without giving any sort of error response. I believe this happens when the internet lags or lost connection temporarily in the middle of the ASACloudSession (before uploading the cloud Anchor) and causes any future writes to fail.

    We experience the same issue.
    Our analysis on this reveals at least 2 different issues :

    SSL concerns of SDK backend subdomains related to IOS14 certificate transparency policy for :
    "*.events.data.microsoft.com"

    For SSL certificates transparency analysis we may see here that at least 3 certificates have only a single CT Log. Apple requires now at least 2 CT for a certificate valid for less than 15 months.

    https://transparencyreport.google.com/https/certificates?cert_search_auth=&cert_search_cert=p:bW9iaWxlLmV2ZW50cy5kYXRhLm1pY3Jvc29mdC5jb206dHJ1ZTpmYWxzZTo6Q0FvUUFRPT0&cert_search=include_subdomains:false;domain:mobile.events.data.microsoft.com&lu=cert_search_cert

    More details on Apple CT policy :
    https://support.apple.com/en-us/HT205280

    When the IOS SDK makes a request, if the SSL certificates returned have less than 2 CT logs, it will be considered "not valid" by IOS.

    2nd issue identified :
    Some machines / IPs on the backend randomly won't answer to requests. Example for the IP : 52.114.75.78 which is on the pool of ips behind "mobile.events.data.microsoft.com"

    I'm looking forward for updates from Microsoft Team.
