I have been using the iPhone App for 9 sessions now and once i finish and hit the "Send" button, the app uploads quite fast the data but then it says "processing" and it last forever there. I have let the iPhone plugged and on to see when it finishes, but it can stay there even for hours. The stats are online and i can view them with the web browser, but the iPhone app still says "Processing". If i want to log a new session i need to close the app and reopen again.
It is not a big issue as all the data is ok and it is uploaded and visible on the website, but it is annoying.
I am using an Iphone6s, and an Apple Watch (but the app is not installed on the watch)
