Hi aqua girl, it might have been, like you said, just a temporary glitch. But it can also be caused by old cached code causing an issue. Your mobile device also heavily uses cached pages and when you update an app these pages have to be cached again. Until this is done it causes extra stress on your device and internet connection, hence your more likely to have a glitch until the necessary pages are re-cached. But who knows as the error message you received could mean anything. But glad it's working for you now.
