Complications that are added to the watch face can not be configured through the Google Pixel Watch app.
Tested with the latest version of the Google’s Pixel Watch app (https://play.google.com/store/apps/details?id=com.google.android.apps.wear.companion&hl=en&gl=US), version 1.4.0.559745056 (Sep 5, 2023) in combination with the Watch OS 4 Preview emulator that comes with the latest version of Android Studio Hedgehog (2023.1.1 Beta 5) and Watch Face Studio (both latest versions, 1.4.20 and 1.5.7).
Complication only has the “Empty” provider available in the Google Pixel Watch app:
Watch faces that come with the emulator do not have this issue.
Steps to reproduce the problem:
Create a new watch face in WFS (tested with 1.4.20 and 1.5.7 – both have the same issue) and add a complication.
Run the watch face on a Wear OS 4 Preview emulator.
Install and run Google Pixel Watch on the smartphone, pair with the emulator, then try to modify the complication settings on the smartphone.
I don’t know if this is the problem of Wear OS 4 being a Preview/Beta version, or WFS. But, maybe you guys at Samsung will know. Any response would be much appreciated. At least, so that we know whether this is just a bug of the Preview emulator that can be ignored, or is that something that must be fixed in the WFS.
State, that same thing also happens to you on Pixel Watch 1 with Wear OS 4 and also write all software versions you’re running. (see from original post)
Strange, it should be visible to Public. Maybe try signing in in Incognito if it works. I know it’s a bit of additional work but for the sake of bringing the issue closer to fix
