Branch IO Deep Linking works only after I clear the Safari history and cache data on iOS

[johnnypi6]

I'm trying to add a sharing feature to my existing app using Unity Branch SDK. I retrieve custom data from initSession function of Branch SDK (Unity).

void Start()
{
    Branch.initSession(CallbackWithBranchUniversalObject);
}

void CallbackWithBranchUniversalObject(BranchUniversalObject buo,
                                    BranchLinkProperties linkProps,
                                    string error)
{
    string senderDeviceID = linkProps.controlParams["$deviceID"];
}

But initSession function seems to work a few times but it returns empty BranchUniversalObject JSON and BranchLinkProperties JSON after that. After a few days of struggling, I found that Safari history and cache data causes the issue. When I clear the Safari history and cache data, initSession function works again as I expected and I can retrieve custom data from Branch deep link.

How do Safari history and cache data affect the Branch deep link? What should I do to fix the problem of empty BranchUniversalObject JSON and BranchLinkProperties JSON?

Logging a ticket to see if we can repro the issue you're seeing. Could you provide what version of the SDK you're using along with some information about the device you're seeing this on? Also are you seeing the same issue on all test devices?

Thank you for your kind reply.

Branch Unity SDK version: 0.6.5

Test Devices

Device Name: iPad Air2 iOS version: 13.4.1

I used the following code to generate a deep link.

public static void GenerateShortURL(BranchManagerCallbackWithShortUrl callback = null)
{
    BranchUniversalObject universalObject = new BranchUniversalObject();
    BranchLinkProperties linkProperties = new BranchLinkProperties();
    string deviceUniqueIdentifier = SystemInfo.deviceUniqueIdentifier;

    universalObject.canonicalIdentifier = "xLeagueShareLink";
    universalObject.canonicalUrl = "http://xleague.games/";
    universalObject.title = MetaDataManager.Title;
    universalObject.contentDescription = MetaDataManager.Description;
    universalObject.imageUrl = MetaDataManager.Image;
    universalObject.contentIndexMode = 0;
    universalObject.localIndexMode = 0;

    Branch.registerView(universalObject);

    linkProperties.feature = "sharing";
    linkProperties.controlParams.Add("$desktop_url", "http://xleague.games/xleague-solitaire-share/");
    linkProperties.controlParams.Add("$android_url", "http://xleague.games/android");
    linkProperties.controlParams.Add("$ios_url", "https://apps.apple.com/us/app/xleague-solitaire/id1480117114");
    linkProperties.controlParams.Add("$ipad_url", "https://apps.apple.com/us/app/xleague-solitaire/id1480117114");
    linkProperties.controlParams.Add("$og_title", MetaDataManager.Title);
    linkProperties.controlParams.Add("$og_description", MetaDataManager.Description);
    linkProperties.controlParams.Add("$og_image_url", MetaDataManager.Image);
    linkProperties.controlParams.Add("$deviceID", deviceUniqueIdentifier);

    Debug.Log("Starting get short URL...");

    Branch.getShortURL(universalObject, linkProperties, (param, error) =>
    {
        callback(param, error);
    });
}

Would you please help me?
