I have noticed in a few threads on the Xamarin Forums (here, here) 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?
