I've just noticed that if it is a different tablet than iPad and smaller (I tested on Nextbook 8), the browser takes a phone version from the published Adobe Muse file!!!! not a tablet version!!!! It only concerns websites created before a new version of the Adobe Muse and converted. If it was done within the last version of a program - everything is ok. I tried to change master pages and resetting automatic redirection (site properties) and nothing works. I can't built this page one more time from scratch. Please help me.
