Hi there! Thanks for reaching out. It looks like a reply to your support ticket went out earlier this morning. Thanks for your patience! Here's the info from that reply in case you missed it.
Not necessarily, but your net earnings can go down. The new Premium plans are a lower Premium fee, with a higher return on your investment.
Because the tiers are smaller than in the older Premium, you can also be upgraded/downgraded more smoothly, with less variation in your expected return- the ROI is very consistent on the new plans.
For example, at your current Premium Tier, you're getting about a 50% return on investment. But with the new plans, you would pay $3.75/month and make $6-8/month- which is a minimum 60% return on investment- but it would be a net lower profit for right now. This could increase over time.
I hope that helps clear things up! I'd encourage you to check out the response to your support ticket for more detailed information.
