The plans and upload limit is uncertain on individual plan and team plan.
The limits mentioned on appsumo page seems to be deceiving one.
It sent me a limit exceed message, i did not exceed even 1000 memo this month.
I was creating a collection of TED Talks youtube videos in one of my collection under a space named 'Learning' After I saved 83 memos in that collection, it threw me a message saying limit exceeded. I am 100% sure I havent even created even 1000 memo this month.

Support is saying, you need to go for Team plan which starts with around 4 dollars per month.

I think, if a plan is offering 1000 memo per month for tier 1. I should be able to use it the way I want it. Even if it means to be collection of 1000 memos in a single space and in a single collection under that space.

One more thing, the limitations and terms nowhere says that it only allows you to create 10 spaces in your login if you are not using team plan. Apart from writing 100 memo collection.

Reply to the first reply:
What if I have added no other collaborator in that space. Will the restrictions still apply?
How would you assume that everyone on the planet knows about how notion works.
Notion is not what I liked from day one of its launch. I did not explore it further.
I request you to spell out this thing in the product page as follows
"You will get one personal space where there is no restriction of number of memos under a particular collection, subject to maximum number of 100 or 200 collections you get as per your plan. However, if you create a separate space (which in our case is considered as Team Space), the restrictions of keeping 100 memos per space if you are using appsumo plans (any tiers) and you will need to upgrade to team plan which will cost _____ $ per month per user." and so on.
