This is likely a model number related issue. I have a Siemens, which, as I understand it, is a Bosch with different styling, since none of these brands actually make the appliances, they're just lending their brand to a separate manufacturer (which is still in Germany FWIW). It also has the "home connect" app.

I have none of these issues. I have a dedicated button for delayed start on the front of the dishwasher. Dedicated "machine care" button. Not sure what the "rinse cycle" is, so I don't know if it has it, but there's a special rinsing-related button on the front that does something that prolongs the cycle. It also has a dedicated "half load" button. It has buttons for every "useful" cycle, like "eco" which is automatically selected when I turn it on. It's also able to go to a menu of sorts where I can configure water hardness, the quantity of rinsing liquid I want (separately from the hardness setting) and some other things I forgot.

The machine was bought new a little less than two years ago and does have the wifi and bluetooth and whatnot. It's also the only appliance I know which supports 5 GHz wifi. The manual also tries to get you to install the app, but it's not needed.
