Is Binance having liquidity issues?

I just had several attempts to withdraw my tokens rejected by the system. Took them about 6 hours to reject each one so I was waiting for over 24 hours already after my final attempt to withdraw got rejected again (this was particularly painful to experience because I essentially got locked out of a very important opportunity for me, unable to buy during a specific period). I've been reading that this has been happening more frequently too. What exactly is up with this platform? Should I be worried that I won't be able to withdraw my tokens at all? Also, do you have suggestions for better exchanges where this doesn't occur as often as in Binance?
