I had previously posted under Android perhaps it may be better posted here, my problem is that the station screen size is too large so can't see the launch button. Any chance of a fix?

Should be fixed in update 1.8.240.
If not, try changing the font rescaling value in Options->Interface. Either turn it off or set it closer to 1.0x (1.5x is far right, 0.5x is far left of the slider)
