Its ok to have limited uses on Free plan, completly obvious, but once reaching the limit, to prevent you from using that feature forever looks like "if you don't want to pay, than go away".
I'd rather have 10 uses per month limit and wait for another month or pay to have more uses, but keep using ClickUp as long as I need, than have 100 uses (that is a pretty low limit) and than stop using at all or create another email if I want to use some features.
I really love ClickUp, it is an amazing tool but I saddly can't afford it by now, as soon as I can I will definitely upgrad. But now that I reached some limits, it seems like its not for me anymore.
