Avoid being closed by Chase (both Credit cards and Account)

Before I go ahead and apply Chase UA explorer next week or two, may I seek for advice about avoid being reviewed or shutdown by Chase?

Here is the list of my approved applications in the past year. 1. 1/28/2024 Chase Marriott 2. 06/01/2024 Chase CIP 3. 1/13/2025 Barclays Hawaiian Card 4. 2/27/2025 Chase UA business

As far as I know, we should wait in between 3 months to apply another Chase Card. But I wonder does it apply to business card?

On a side note, I recently opened a Chase Biz checking then transferred 20k from BOA right away. Then the account was closed due to the reason my personal checking was closed back in 2020 (although I reopened it successfully in 2021 and continuing) Any thoughts about this situation? Was it triggered by the big transfer or the fact my account was closed in the past?
