I love this mode too but unfortunately 20 is so Glitchy for me on android that I get super frustrated with it. Best I've been able to do is like 200k in a round. Hoping they get these bugs worked out soon
Imo keepers suck and they cost way too much to upgrade. I think they play like 3 star players too. To answer your question though, I don't think it really matters. You'll use them for a month tops and then move on to much better players that you can max out for a fraction of the cost.
Pitchplease use your same credentials to back your 2020 team up that you did with 2019. Once you do that you should be good to go. Has to either be linked to your FB or your email
Had the same issue last year. Ended up losing a 120k team early in the year. I got locked out completely. Customer service will tell you are only allowed one account per device. If you want to run 2 teams with no problems you'll need a second device.
I should be getting the vip invite soon. Been grinding since the beginning and spending the money. Hopefully they'll reward me for it soon since we only got a handful of months left to play this version.
