Sadly, it's mostly an iFly limitation. Lack of copy and paste capability.
Coincidentally, I noticed this again about an hour ago. Someone on an online forum was asking about a SOCAL TEC route. So I went to one of the two dedicated SOCAL sites to take a look at it. One if the options is to copy the route. Same thing for common IFR routings. Multiple websites have them and, of course, we can copy the routing.
I have a half dozen EFB apps currently loaded on both my iPad and Android tablet and phone. I've also used others. There is only one I cannot paste the route into.
@George, yes, that's all it takes.
