Foxah Pixel 7 support is a work in progress. Probably starting today. Google uploaded the AOSP source code supporting Pixel 7 some time last night (i.e., it wasn't uploaded when I went to bed, but appears to be now).
When its ready, you'll see some announcements in this forum. Pixel 6 took several weeks. Pixel 6a was near immediate due to the fact that its not much different. The Pixel 7 is more different, but hopefully not significantly enough to cause a major delay.
Cross your fingers that its an easy and fast device to support.
