SHAC not responding to iPhone inputs

Hi All,
I have just found that my iPhone can no longer control my system through the SHAC web interface on my iPhone. Not sure if this is a problem with the system or my phone. I think it has occurred since the latest iPhone update, but can't be sure because I was away from home for a few weeks am the update happened during that time.
When I open the web interface is showing the correct status of the relays, but when switching them on the phone, they don't actually switch on the cbus system, and when switching via a switch on the cbus, it isn't updating on the phone. When I log in again the status has updated correctly again.
I have confirmed it is working when logging in on a computer, so it just seems to be a problem with the iPhone connection.
Is anyone else having trouble using the SHAC web interface on an iPhone or have any idea what is going on?
Cheers,
Clayton

 

Quick update, this seems to be an issue with the Safari browser only, it is working in Chrome and DuckDuckGo on the iPhone. Guessing something changed in Safari in the recent iPhone update (iOS 26.1).

 

After seeing this I tried for the first time with IOS26 and it failed with a white screen.
But, after trying a few times and using the setting 'Clear History and Website Data' it now works, no idea what was going on.

 

I have a similar problem since iPhone updated to iOS 26
Shac appears ok and reads cbus ok but will not send commands to change anything
Has anyone else had this happen
Thanks

 

Yeah I've experienced similar issues. Our phones and IPADS that aren't always logged into the SHAC seem to have the issue, but two IPADS that are on wall mounts and are always logged in, seem to be ok.

 

My old iPads that are wall mounted and connected via same wifi both working ok
Samsung phone also working ok
So must be something in latest iPhone update I guess
Although not many replies so I guess not many people affected
Also ok using chrome on iPhone!!!!!
Thanks for reply

 

We also have old iPads wall mounted and they work ok with shac.
Also Samsung phone works ok.
So using chrome on iPhone as previous suggestion and working ok
So guessing it must be something to do with latest iOS update?
Not many replies so I guess not affecting too many
Thanks for reply

 

I tried the "Clear History and Website Data" for the Safari app, and that works for one time logon, but the next time you log on again it doesn't work. Need to go and clear data again. Definitely something changed with the latest iOS update, as it never had this issue previously.
For now my workaround is a shortcut icon on the home page directly opening the link in google chrome.
Not sure why apple constantly break things with their updates!
