Orbi RBR20 - Armor VPN compatibility with IOS apps

Since subscribing to Armor services on my router and downloading the BitDefender software on all of my devices, I have experienced app issues on my wifi.  Most cases, the app would load, but would not function properly.  Actual error messages vary by app based on their error handling.   I have found that in many cases, toggling my wifi off/on did the trick, presumably re-establishing the VPN session.  Recently, I have noticed that these issues are not easily resolved in this manner.  I now need to go through a multitude  of ever increasing intrusive means of recovery.  Beyond wifi settings, I try shutting down the app and reloading, power down IOS device and restart, delete and reinstall app - and today, reboot my Orbi - after discovering I could no longer logging into the router.

My concern - this appears to be getting worse - is this incompatibility as IOS continues to evolve?  Is it a matter of Armor catching up?  Anyone else have similar issues - I've not found anything - anywhere - regarding similar issues.
