Besides the CIQ app, you can also use the Connect app to manage the widgets, apps, data fields and display designs (watchfaces) that you can download from the store.
This also works for me. However, NOT with the display designs.
The Connect app constantly brings the error "network connection error". But only with the display designs. I have had this problem for a long time. Also with the current Connect and IOS version.
So it is not due to a temporary server failure. And everything else works as well. The error is limited to the display designs only.
Would be nice to get as much feedback as possible if you can reproduce this problem.
thanks already.
