Ring Intercom not working

Hey there! I received my Ring Intercom a day early (hooray!) but I'm having issues with the installation. The process itself is really simple and I'm familiar with electrical wiring so the "do it" part of the installation wasn't an issue. My current intercom is from **Siedele, model number HTA 811**, which I selected in the installation process. Here is what the app is telling me to do while using the included **Cable A**: (Had to remove this screenshot since new users can only post one picture, I posted it in a comment below) And here is how I wired it:  Seems correct to me? Just to be sure, I re-did the wiring and double checked each wire by pulling on it, there really shouldn't be any issue with the wiring but I can't think of anything else. Once I continue the setup in the app it tells me to go downstairs and ring the bell (even tried repeatedly), which I do, and I can hear it ringing inside my flat - but after a while the test fails and tells me to check the wiring, if any cables are loose , etc. but as you can tell from my pictures and the multiple checks I did, something is off. On the picture you can see there is one preinstalled yellow wire that isn't connected to the intercom, but it was like this once I opened the intercom for the first time, and the old intercom works without any issues so I don't think this causing any issues. I realise this product officially launches tomorrow and not many people have it until then, but maybe someone here can spot any issues or if there are any Ring staff here they might be able to help :slight_smile: Calling the hotline doesn't really do much since all they do is tell you to check the wiring and so on, which the app itself already did and there isn't much they can do sadly... Anyway, thanks for reading and I hope somebody can chime in and help me out!
