trueplay does not work with sonos s1 and ios18.2

I have two setups of sonos products. I have them for about ten years. One time I upgraded both sets to s2. Since then super slow, so yesterday I decided to downgrade to s1 again. Better response times since then and everything works but… I am unable to perform a trueplay tuning through my phone or any phone running iOS 18. it immediately throws a network error. I tried to find out what is was but to no avail. 
I could do a tuning by using a older iPad running iOS 16 without any problems. My guess is that the problem is not in the Sonos network or WiFi network but in the iPhones and maybe a security setting that prevents trueplay tuning?

Can someone help me with this?

Were you able to Trueplay while using S2?

Yes. The s2 worked flawlessly but super slow. Getting music to play took about 10-12 seconds as did the volume change. Now 4sec.

Four second S1 response seems long to me. Describe your network for us.

ADSL router serves as a dhcp server. A mesh WiFi network of tp link decos. (Had netgear orbis before but they really sucked). The WiFi network is setup as access points. 
I guess the 4 second response is when it needs to access the internet for music of radio. Internal response, eg volume change is immediate. 
Accessing the Sonos cloud service is not that fast. 
adsl speeds are 100+ down and about 20 up. 
also what I noticed is that only the playbars show in the client list on the deco software. The rest seems hidden. The Sonos app claims all speakers are online. The dhcp server shows all Sonos clients.

All SONOS devices will be visible in the system settings area. On the Home screen a soundbar, its surrounds, and SUB(s) will show as a single Room.

With respect to the Deco: Surrounds and SUB’s will connect to the soundbar via a private 5GHz link. The  DHCP server will be aware of all devices, but the surrounds and SUB’s will not use the WiFi when playing audio.

I know that this is the case.

still it is strange that a ios16 device is able to perform a trueplay tuning while an ios18 device is unable to do this.

What is makes the older os work?

The older works because the Sonos folks have had time to test it and develop the needed software settings to let it function properly.

I don’t use Apple stuff here but I’ve kept one Trueplay compatible device around for running Trueplay. Learned early on that being listed as “coming soon” means a decision to support or not is coming, not support.
