Thank you for connecting with us and sharing your concerns. I double checked to see if any other new users are reporting this issue, and I wasn't able to find any widespread or ongoing concerns. Typically, when it's not something that can be replicated by other users it is a local issue.
Most commonly, it is caused by a caching or network issue, so let's quickly rule that out with the following troubleshooting steps:
Try clearing cache/cookies of current browser
Try from a different, up-to-date, browser
Try from a different network connection
Once you do that can you please try re-connecting to the apps once again? If the issue does persist at that point, please grab a screenshot for me of each step you are taking along with the error that is finally presented.
I look forward to your reply,
