My wife's iOS is still working so I know the notifications are getting out. My control4 has the same thing, started about a month ago or so. Now this Android
Mine also, not sure when they quit. Android and the latest ver. of BI, BTW no Bitdefender or anything like that just VM machine that can reach the internet. Updated today to 5.9.5.4
For a wireless shot to the outbuilding I'm using ubiquiti ns5ac. That's how I send my network to my shop. I've setup this system to a gate 2500 ft with the remote end on solar only.
