What happened to trading with fellow Allies in the PM. Tab?

(I am a mobile player)Since Update 1.5 came out I have enjoyed it on mobile although some bugs when I have enhanced graphics on but that's not why I am confused and concerned as of the 1.5 but recently I have noticed that the PM. Trading option for resources and troop units isn't there anymore. I noticed this after I was going to trade with a fellow ally in an 100 WAW game (speed run verison), resources and some tactical bombers but noticed the tab wasn't there only thing there was relationship trade and province but no resource and troop unit tab so I was very confused so I looked at the update and saw that nothing was done with trade so immediately came into concern (nor was my ally able to do it no idea if it's a big or what please help?
