could there be problems in the future with this address?
Yes. Certain services like blockchain.com wont recognize it. And thus wont see your payment etc. Ive had troubles with certain payment processors, but these will likely update their code to also see and accept bech adresses in the near future.
But if you mean if your funds will ever be stuck on the adress; no it is highly unlikely that the network will somehow try to get rid of bech adresses.
