Growing a network for 20 IG only vs 20 IG/FB/Twitter combo

Thank you for this community.

I have a new MP user and I love it. Have only been using it on 2 accounts. One has 50K other has 1500.

I was thinking about planning 20 IG pages alone without messing with the other platforms

but since I want to do this, should I just go ahead and also grow on other platforms?

I dont know what I really want to do. Just asking if it is a shame to just grow 20 IG accounts with FB and Twitter

thank you again

I suggest starting with IG at first since you know your ways around it and once you finish setting up the 20 Instagram accounts then you can grow slowly with the other platforms one by one at a time.
