Uploading image error in playconsole


While uploading watch face, there’s an issue with uploading image for 10 inch tablet.
And this category is mendatory, I should handle this one.

I used to upload image size as 1024x500px for all devices.
but, 10 inch tablet image doesn’t match well with this image size.

Which size should I upload for 10’ tablet?
and one more question, isn’t it too slow accessing google playconsole recently?

Erro messsage keeps popping up like below ㅠㅠ

10-inch tablet screenshots requirement as follows:
“Upload up to eight 10-inch tablet screenshots. Screenshots must be PNG or JPEG, up to 8 MB each, 16:9 or 9:16 aspect ratio, with each side between 1,080 px and 7,680 px”
Also note, you can skip tablet and chromebook screen shot. I never add those.

Nope its not slow at my end. Just works fine.

Thanks a lot for your info!!
