iOS app无法唤起微信小程序，每次唤起时，都显示这个页面然后就回到app了，跳不到微信小程序中；

Universal Links: https://cdh5.ec.fkdxg.com/

唤起的code:

WXLaunchMiniProgramReq *launchMiniProgramReq = [WXLaunchMiniProgramReq object];

launchMiniProgramReq.userName = @"gh_63b687896042";

launchMiniProgramReq.miniProgramType = WXMiniProgramTypeRelease;

[WXApi sendReq:launchMiniProgramReq completion:nil];

Log打印如下：

wxlog:send req[<WXLaunchMiniProgramReq: 0x2809a9280>], appID:wx6ce257685c23f9a1, universalLink:https://cdh5.ec.fkdxg.com/, sdkVersion:1.8.6.1
