Can't access router in Orbi/Netgear App

I have the RBR10 — Orbi AC1200 Dual-Band Mesh WiFi Router.  Since last week, I've been unable to log into my Orbi app on my phone because my "admin password doesn't work" (even though I have it saved on my phone and did not change it).  I can't use the QR code on the router to access the linked code within it, and I can't go to routerlogin.net or its alternatives and try to change my admin password from there because those options don't rcognize anything I do, even though I'm typing the serial number from the router exactly.  I was, however, able to log onto this site without issue.  I'm being told that my wifi connection has bad security as well, but again, I can't do anything since I can't access anything Orbi-related.  I still have Internet, though.

Has anyone else had a similar issue recently and how did you resolve it?
