Hi, Creator team,
I have some issues with my app TradeMaster. I believe I have shared edit to support.
If you run, for example, the MASTER SHIPMENT TRACKIGN View under MERCHANDISING VIEWS section, it often takes over a minute to run the view.
Sometimes an error is generated when running it.
Is it normal?
Our users are complaining and I would like to see if it can be improved.

Thanks.
