Appcenter: Test Crashes not being submitted to AppCenter

[comply365dev]

What App Center service does this affect?
Microsoft.AppCenter.Crashes

Describe the bug
Following the SDK installation instructions, and using "Microsoft.AppCenter.Crashes.Crashes.GenerateTestCrash();"
the test crash does not push to AppCenter

To Reproduce
Steps to reproduce the behavior:

1. Create new app in AppCenter
2. Create new Xamarin.Android app in visual studio
3. Follow SDK install instructions
4. use "Microsoft.AppCenter.Crashes.Crashes.GenerateTestCrash();" to generate crash (can also just throw an exception too, that doesn't work either)
5. re-open App and see error in "Debug" section below when it tries to upload it.

Expected behavior
Should send the test crash to AppCenter

Further Debug info

1. Using AppCenter.LogLevel = LogLevel.Verbose
   "App Center SDK configured successfully." is printed and the payload doesn't look malformed, it's just the default "type":"Microsoft.AppCenter.Crashes.TestCrashException","message":"Test crash exception generated by SDK"

@comply365dev do you mind starting a conversation in the blue chat bubble on the bottom right of App Center and link this conversation? This will connect you to our support and engineering team who can take a closer look at this for you. Thanks!

Figured it out w/ the help of Jorge Medellin. Local device timestamps was set ahead of local time. Putting this here in case anyone has this issue and searches for NoValidLogsFoundInLogContainer
