I have a Samsung double oven that the app no longer talks to. When I try to add it back to the app, it cannot find the AP. It sees the AP just fine when I look at the oven control panel. I've removed and readded both my refrigerator and cooktop and they find the AP just fine. I'm currently using an Galaxy S7 running Android 7. I've already tried reinstalling the app but to no avail.
I think the oven's firmware may be the problem. I went to a local retailer and tried to connect to one of their floor models and it worked just fine. It was also running an older firmware than mine.
My current firmware is TIZEN 2.3.0 (WALLOVEN.PP.US.20170417.0637)
The firmware on the store unit that is working is TIZEN2.3.0 (WALLOVEN.PP.US.20160811.1833)
Thanks for confirming! I'd strongly recommend getting in contact with our friends in the US.
They'd be able to provide you with the relevant support as device parts and functionality can differ from region to region.
