You can check it with a recent enough iw:
  iw wlp2s0 info

It should tell you channel bandwidth you are using.

Maybe ath10k or your AP has a bug that causes wrong capabilities to be
negotiated during association.

You could try re-configuring your AP (to slower speeds) or force
wpa_supplicant/ath10k to not use vht or ht modes at all and re-testing
if it helps.
