We have multiple layers on Portal that workers use in ArcPro for editing and reference. For some reason, when they reopen their projects after closing they often lose connection to one or more of the layers (seems pretty random). Has anyone experienced this before? Interestingly, they can't reconnect to the service using the repair data source menu, it gives an error. They instead have to pull in a fresh copy from the Portal. We just upgraded our Enterprise deployment last month and republished all these layers.
