I have noticed in a few threads (here, [here(https://forums.xamarin.com/discussion/comment/143571)) that people were having troubles uploading an app to Xamarin Test Cloud. Those posts were old but none of the solutions worked.
Error I get is
Unexpected character encountered while parsing value: <. Path '', line 0, position 0.
I created a new project with the same bundle ID and the same Info.plist and I am able to upload to XTC with that. But clearly isn't the app I want to test (though I did try out text input and screenshots, this system is awesome).
There is nothing else on my end that I can think of causing the problems. I did notice my .ipa file was about 230mb but had not seen anything about a max filesize for XTC.
I tried to use the --debug option to get more info when I ran the same command to upload from terminal but it did not help. Any suggestions what to do or why XTC servers may be erroring on my files?
