Orbi RBK53 System Acting Odd Lately

I posted this yesterday, but it seems the thread was locked. If something is wrong with what I am posting, please let me know, as I really would like some help.

I have an RBK53 system with the RBR50, 2x RBS50's, and a RBS20 I added later. The two RBS50's are hardwired back to the RBR50, while the RBS20 uses a wireless backhual as it is more remote (@40 feet from the nearest satellite, and two floors and about 50 feet straightline from the router). They have been up and running just over a year with minimal issues. In December two things happened that may have lead to issues, but since they were simultaneous I am unsure what lead to my problems.

A. The Armor subscription "auto-renewed". I say that as the money was taken through Bitdefender's store front, but the service lapsed anyway. They claimed I chose the wrong product, but since I chose nothing and it auto-renewed, I don't see how I screwed it up. Took a while to try to resolve with them, and in the end I got a refund and gave up the renewal since it was still showing "Security Off - Expired" in the app and the web interface after they 'helped' me. I eventually checked out on a new subscription through the Armor app and it is now showing security is on.

B. I got an email in December about allowing the critical firmware updates to apply, but I wasn't getting any pushed to the devices. After a couple weeks of checking, and during the whole expired Armor issue I finally saw that the website had V2.7.1.60 for the RB_50s, and 2.6.1.38 for the RBS20. I applied them, and then the RB-50's wanted to automatically update to 2.7.2.102, which is where they are now.

The issue is that the app and the web interface are hit or miss as to what they will do. Wondering what my best path forward would be, and if a firmware rollback is typical or even allowed... I have not tried yet, but I have had routers where you could not go backwards. Hoping to avoid a reset due to the number of static IP addresses, Dynamic DNS, and other settings that would have to be redone, and my inability to load all those pages reliably to generate a backup right now. Advice?

The issues, none of which existed before recently:

1 - The app and main page of the web interface will show random number of satellites, from 0-3, but I am sure theat the three are all still functioning since my coverage is good and devices hardwired to the satellites stay functional.

2 - They will show random number of connected devices, between 0-50, with 50 probably being about right, and 0 not being correct since everything seems to be working and with three kids remote learning right now I am sure I would be hearing complaints.

3 - Somewhat randomly it will not load some pages in the router web interface, sometimes with long swirly icons that never go anywhere, and sometimes with a 500 error.

4 - If I try to go to Advanced -> LAN Setup in the web interface to look at the static IP addresses that have been previously set, it will typically load slowly, flash the contents of that page for a split second, and then go to the ADVANCED Home page.

5 - While looking to do a firmware rollback, I found that page is screwed up, showing me with dozens of satellites. See image below, where the first 4 are real, and yes one is named Squee, but there should be a single Squee. I didn't capture them all, but by the size of that scroll bar on the right, trust me that list goes on for a while.

To address other network related configs - The system is connected to the Internet via a Netgear CM600 cable modem. I have two simple Netgear switches near remote endpoints on the network, and right at the router I have a Netgear GS116Ev2 managed switch which is not setup to do any management right now (used to use it to do link aggregation for two NAS devices).

Thanks!
