I am all Apple and have no issues.  There have been several similar posts to yours many of which were easily solved.  I collect these :-)

Here are the collected comments - work through them and see if they can sort you.

             APPLE CONNECTION ISSUES

The setting that is critical on the Hub 3 is to have Wi-Fi Security set to WPA2-PSK
this will ensure a fuss free connection with Apple kit.
———————————————-

After a MacOS/iOS update, it may auto turn on Automatic Proxy Discovery for all Wi-Fi networks - so for MacOS - turn it off in network settings.  In iOs go to Settings>WiFi> tap the blue”I” icon and scroll down and make sure Configure Proxy/‘ is set to off - also that Configure DNS and Configure IP are set to automatic

===========
Check this...  no connectivity on Apple kit may be a MAC filtering issue for Apple devices

Also, are you running a VPN - if so turn it off and see if that helps - also disable “Private Relay” if that's switched on in your iCloud settings on the phone/mac.

Switching this off solved the speeds issue here….

APPLE WIFI SCANNER

Get Apple's Airport Utility for the iPhone. Then go ... Settings->Airport Utility scroll down and toggle "Wifi Scanner" to on (green). Then open the App and click on the Blue WiFi Scan icon at top right. then hit the blue “Scan” icon - when you are in the location of the affected device(s).

Data will flow in continuously updating, with the SSID’s showing with the "strongest" i.e. "best" signal at the top of the list - they have the highest RSSI values - and the channel numbers are also shown.

Only use channels 1,6,11 for the 2.4 GHz band - choose the best channel for your location (least congested ) and switch your SSID to that.

•    Access your Hub by navigating to 192.168.0.1
•    Login with the default login info (on base of Hub) unless you've already updated it.
•    Go to Advanced Settings > Wireless > Security

•    Disable the Smart Optimisation on the wifi bands.
•    Under Wireless Frequency 2.4GHz change the Wifi Network Name (SSID), suggest append _2 to the end.
•    Repeat for the Wireless Frequency 5GHz, suggest append _5 to the end and click on Apply changes
•    Try to avoid spaces and periods in the SSID names as they can cause issues with certain devices.

This is to split the SSID's away from the single SSID used by VM.  Once split you can change the channel as mentioned by jbrennand   

HOWEVER, if you are using the Pods, or the Connect App, this will not work.  The Pods need a single SSID and Smart Optimisation on, and the Connect App will reset the Wifi settings to suit the Pods.

The Apple weak security warning usually occurs if the older WPA-PSK
is enabled either on its own or combined with the WPA2 & WPA3 encryption modes.

Ok thanks again for the help so just to clarify it’s ok to change it from WPA2-PSK (seemed to be causing the drop in WiFi on my iPhone on iPad) to WPA2-PSK/WPA3-SAE (even though I get weak security warning)

Sorry also to add when I check to service status on the app it keeps saying there’s “Intermittent signal in your area We’re looking into it. Check back here after 24 hours” and my tv status says “There are issues affecting your TV service” but we don’t seem to be having any issue with the tv just the WiFi signal dropping constantly for the last few months on and off. I’m not understanding what’s causing this as the router was only replaced 2 years ago.
