App continuously fails to connect multiple speakers in party mode together. I don't understand it has worked great for so long I go spend over $1,200 on 3 new speakers and they won't even linked up because the app doesn't work properly and constantly closes. If I don't find something convenient very fast then I will be done with these and and by JBL speakers because their reviews are outstanding. I'm trying to stay loyal to Sony as I have been for at least a decade but this is ridiculous.
