Why can't I sell on PancakeSwap?

I've been attempting to sell my tokens on PancakeSwap, but I'm encountering difficulties. Could you please elaborate on the potential reasons behind this issue? I've checked my wallet balance and the contract address is correct. Could the market conditions or liquidity pool depth be affecting my ability to sell? Additionally, is there a specific time window or minimum amount I need to meet in order to successfully execute a sale? I'm eager to understand the underlying causes and potential solutions to this matter. Thank you for your assistance.
