Help with ebay listing how to add accept best offer

Hi I was wondering if anyone could help me, I'm made the mistake of upgrading to a business account,  so now I have had to make a new account, but everything seems to be working differently now, when I make a listing I can't add accept offers on the mobile app,  I have to save it as a draft and finish it on the laptop,  which is really frustrating if anyone could help me figure out why this is happening I would really appreciate it,  I have tried to contact ebay multiple times with limited success in the support they are giving,
