Iphone XS Max MT5 not being able to trade

 

hi since i changed my phone from Iphone X to Iphone XS Max, I'm unable to use the buy/sell options nor even the trade options pops on the app itself which makes me believe that there is a bug. I reinstalled it several times but no use my broker told me to use the desktop version for now and contact support for MT5 any idea how i can reach them or what do I need to do ?

appreciate the feedbacks.
