This year it has been very slow it seems.  But to respond to your question, speaking for myself only, I never use a phone for fantasy sports.  Never.  Must have either desktop, like now, or my Apple laptop.  I was away all weekend and waited to get to the hotel at day's end to fire up the laptop.  
Millenials are all into the phones as form of communication and everything else.  We of the more seasoned age prefer to see the big picture.  Now you know.  That will be three dollar please.

I use my phone to read newspapers, email, Misfit, play Spotify, etc.  The reason I stay away from fantasy sports on the phone has more to do with the inability to jump around efficiently among various websites (fangraphs) and Google spreadsheets from a phone base. I guess it could be done, but for me it is much easier to just keep a bunch of tabs open, especially with my alter ego being the commish.  He needs to keep up with the picks 24/7.  Rough job!

We need to do a better job of picking, three picks a day won't get it done. Let's go it baseball season we leave are wife's for six months.

It's been so long since I made a pick. I've changed my pick 10 times. Let's get going

What about a one-hour this weekend or next?

Round #8 Pick  2/27/18 about 1118 hrs
Round #9 Pick as of 3/2/2018 1125 hrs still waiting.  

Unreal..........................................

Yes, that is the way it is supposed to be, and has been in past years.  This year seems different.  Partly due to 14 managers instead of 12, but also we are suffering through more of these long waits for some reason.

I can only assume that sooner or later managers will get serious as the season approaches.  But at the rate we are going, it could be down to the wire.

It will take a league rule change to shorten the 12-hours, which is intended for working days and overnights only.  During the evenings we expect to get six or seven picks per night normally.
