I have had a Deco X90 router and mesh for a couple of years. It has the latest firmware. Works great. I set up a port forwarding rule (see picture) that works fine. However, I now want to delete the rule and I cannot. I have tried changing the rule, using the delete process, rebooting the router and mesh, etc., but it will not delete and close the port. Is there any way to delete the port? This is an obvious bug and a major issue if you can't delete / close forwarded ports.
