I use to play with metamask in my ipad last year. It was very unstable, i had the Ipad air 4th gen and after few updates metamask was working fine there but for last three to four months i am unable to use metamask on my ipad. Only direct transactions work on metamask ( in Ipad ).

Maybe in future developers will fix things and cross platform usage will not be a problem. I now do most of my stuff on Asus gaming laptop that i bought this year in march.
