Can I run a giveaway via rafflecopter on my FB GROUP? I’m trying to get more GROUP members. I’m almost at 10k. I also have a FB Biz Page, but it only has 1650 followers/likers. My site is thru Shopify, where all customers order from, but I’m trying to grow my VIP FB Group, as that’s where all the “action” is. Please help! I’m at 9,920 members and want to do a big 10k giveaway event ASAP! Thanks! Oh- one last thing- can I install this from my iPhone 7s+? Or must it be done from my laptop? Can’t find your app in Apple store...
