Remote issue

Hi, i have just installed the Krypton/Estouchy version on my Rasperry/Osmc, and i have two issues and have not found any lead on how to solve them.

First issue is quite simple, i use my tv remote to get things moving… but the only key i have not figured out is the “close window” one.

Second issue is also bugging me: my ios apps are not responding as they do not “see” the Rasperry, althought Zeroconf is on and IP address is correct (worked fine before/ but upgrade ruined it). All i get is a “could not connect to the server” message.

Thanks for your help.
