How Much Grandfathering will Grandfathered pricing offer?

I’m interested in locking the price before it’s increased on April 17. I have a dilemma in deciding on the best plan. The question is. If I become a paid client before the price increase and decide to change the plan in the future, will the plan pricing be grandfathered?

E.g.,
I sign up for Pro at $20/m, and in a few weeks, I decide to upgrade to Elite. Will I be paying $50/m or $69/m for the Elite plan?

Thanks, for thje free plan has none of these features?

what about my second question, pls ?
2/ I you choose an early bird offer, will you be locked in to the early bird prices? ie if you want to upgrade later on, will the still recive the early bird price on the upgraded plan?

This is about how you are are locked into the price you decide for now.

ie if you want to upgrade later on, will the still recive the early bird price on the upgraded plan?

That’s different, and no if you decide to upgrade from Pro to Elite in January 2027
we will certainly not give you the Elite price of March 2023,
that’s not how it works - anywhere in the world.

You can benefit from locking in the current early bird prices now,
but it you change things around that benefit is gone.

See the same question answerered to @maxv here.

You lock in the price and plan you buy now.
If you change things, later, you have the prices of later.
