As far as I can tell, it's now impossible for someone to get a Portuguese bank account remotely. We've been waiting almost 3 months on Atlantico who tell us each time we call that we are in the final stages (we've been this way for 2 moths). My lawyer tells me that it's not possible to do with a power of attorney either. We decided to go ahead with the visa application anyway (we went to our local embassy in Panama last Monday). We showed the the Atlantico emails that show we're "in progress" and they didn't say anything so, I don't know.
Thoughts? Advice? Are we going to get rejected?
