On-Device store - New options do not appear when I edit my App Description

I see the option to add images on all my apps.  You have to enable the new images.  Here's where you do that:

Setting activity types is only available for data fields.

Thanks Jim.

I missed that :-(

Enabling that lets me add On Device store icons, but I still don't get the option to select associated activity types as described in the announcement. Is there something else I need to do ?

Thanks

Activity types are only available for data fields.  Are you looking at a data field or another app type?

Ahhh.... Mine is a watch app so I guess that doesn't apply.

Thanks again Jim

One more question.

I was able to add a 128x128 64 color image, but attempting to add that same image for the 128x128 24 bit color image fails. Can you tell me how to save that 64 color image as a 24 bit color image ? I'm working on Windows 10.

Thanks

I found an online converter that produced a 128x128 .bmp file with 24 bit color. Uploaded that for the 24 bit image and it was also rejected. 

Thoughts ?

I also couldn't upload the same image twice. It seems to have some validation that only allows different image. What is not clear is if that's a bug, and we rather upload a different image (or the high-color devices won't see the icon) or it is OK, if the icon anyway is less than 64 colors, then a devices will us that icon.

Can you see your icon in the on-device store? Is your app public (non-beta)? Can I try to see it on Edge? I have this problem: forums.garmin.com/.../
