Yes I have read that post. If I am not misunderstood, that post told that app designed for tablet must be set specifically in manifest file, otherwise it will be set as app for phone.
My situation is different, I didn't set anything on manifest file, but on play store, my app has set only for tablet and wouldn't appear as app for phone.
I use default manifest file (B4A 3.8), which I think, target SDK is 14.
The problem is, i want to appear that app as app for phone and for tablet and how to set it.
EDITED
I didn't put screen shot in phone area on Google console, my mistake, could this is the reason?
Republished again my app and wait for result.
