Bitcoin transaction moving to HW Wallet still pending

I transferred some amount of BTC from asked an exchange to send some amount of BTC from my account to a hw wallet and the transaction is pending even after 4 hours and it is very concerning.

A test transaction of minuscule amount before sending my treasure (savings of around 4 years) went through within 30 min or so.

Particularly concerned cuz I updated the firmware of my hw wallet and then had to restore the accounts using the seed phrase. This created a new address for receiving BTC and I had doubts if I should send the big amount to the new address or not.

Please say that I have not screwed up a big time….
