I have just tested this app with both my enterprise account and a free account and have been unable to get it to successfully scan a document to a Spark Space. The scan says it's competed but when I tap message the machine print a page that says there was a problem with the URL. I also got the attached errors during my tests.
We see this error (problem with the URL specified) occassionally when the Device date, time or time zone are off from your current location. Please check that they are set correctly and retry the app if they need to be adjusted.
If the date, time and time zone settings are all correct, please reboot the device and then retry the app. If the error still occurs, you should contact Customer Support for the App. If you go into App Details, there should be information/a link to connect with app support.
If you're having trouble connecting with App suport, just let us know here and we'll search for an alternate contact for you.
I installed and launched the CISCO Spark App in our lab. I was able to successfully connect with no issues.
Note, I did download and install the CISCO Spark Desktop App. I activated my account and successfully logged into the Desktop App before I logged in at the device/MFP. I'm not sure it that would make any difference or not, but I wanted to share this information with you.
Please let us know if you need any additional assistance resolving this issue.
