Hi Kevin,
Sorry for the delay in getting back to you on this issue. We are still finalizing a solution, but a work-around for now would be to change the symbol used for the features from the 'flag' being used now, to something a bit more simple like a simple shape. We will aim to include our final solution into the next release of AGOL. If you need the fix sooner and are able to host the application yourself, let me know and I can send you a version that includes the fix.
