Why are two new Edge devices restricting the screen layouts for datafields?
There isn't even a full screen (1 Field) option as there has been on every Edge device up until now

I have the same issue and my simulator is not working properly when I want to trigger the app settings I only see a white screen. With all older devices, even the fenix8 Pro it is working fine... Is this a bug in the code or in the simulation of these two new devices?
I mean it should be obvious that this is a bug in the simulator. NO WAY Garmin doesn't allow full screen in the real device.
It could be a bug in the sim device config [simulator.json] / device reference [which both show the same thing- I assume they are generated from the same source]
DCR's Edge 850 review shows a 7-field layout, which is not in the list above:

Then again maybe it's possible they've changed something for the release? Not the first time certain things would be changed, added or removed post release.
It does seem like it would be a strange change / limitation.
It's not exactly the same thing, but a couple of years ago, a Venu Sq update broke the *detection* of a 1-field [fullscreen] layout for CIQ data fields. What I think happened is that a lot of these fields will detect a 1-field layout by assuming that if data field Dc size is exactly the same as the screen size, it's a 1-field layout, and if the size is different, it's not a 1-field layout. In this update, Garmin probably made the 1-field layout Dc slightly smaller than screen size, so a lot of fields started assuming they were in multiple field layouts and rendering incorrectly. After people complained, Garmin reverted the change.
Maybe the easiest thing would be to post a bug report in the CIQ bug reports forum?
Following CIQ device specification, that's not a bug, it is wanted:
https://developer.garmin.com/connect-iq/device-reference/edge850/
I can imagine, this is one step Garmin is going in direction to block developers to add castrated features.
It is 100% clear to me, without 1 field layout Edge 850 is completely useless to me.
I hope this is opening developer eyes and developers shout at Garmin so that Garmin doesn't think about such bad things anymore
Following CIQ device specification, that's not a bug, it is wanted:
I have always assumed that the device reference and the CIQ device library (CIQ/Devices > simulator.json, compiler.json) are generated from the same source, same as the CIQ API docs and type information (CIQ/Devices > *.api.debug.xml).
If that's true, then the device reference saying the same thing as simulator.json doesn't prove that there isn't a bug.
It wouldn't be the first time that something was wrong in simulator.json.
As I said above, DCR's review shows a 7 field layout for Edge 850. simulator.json and the device reference do not show a 7 field layout. In that case, either:
- simulator.json and the device reference are wrong
- something has changed in the device for production units (as opposed to DCR's review unit)
My point is that if simulator.json / the device reference can be wrong about the 7-field layout, they can also be wrong about the 1-field layout.
I'm not saying they are wrong, but only that they could be.
There is a IQ datafield for a single field layout (which is missing in the simulator), which the developer made downloadable for Edge 850 on the IQ store.
One user wrote a review, complaining only the little too big fonts, but apparently he was able to download and show this single IQ datafield on the screen of his 850.
That‘s a proof for the buggy simulator.json!

BTW: there is a good workaround to create a single datafield for the simulator here:
