Is the UB layout completely different from the AP layout?
yes it is this is why one default cereus layout doesn't work for both sites.
Could you please create a ticket on the Support system and attach a screenshot of your table.
I've created a support ticket but haven't attached a screen shot. Its just he all the standard table layouts on UB. I'm sure the support staff don't need a screenshot from me to know what they are.
Are there options for the appearance of tables at UB now?
If you mean to make the UB layout the same as AP no not that I can tell.
Aside from the different layout and conflict with popup stats and action buttons another problem I've just noticed is that when the players hole cards are flashed at the end of the hand the players on the left have their hands partially off the screen so you can't see the full hand. (in omaha 6 max).
I've put all this in the ticket comments so hopefully it will be addressed soon.
