can you confirm you are in the right wallet in Trezor Suite? Do you see the same ETH address (under your ETH account) that was used to send the transaction?
I can confirm that it was the right wallet and I could see confirmed transactions.
The issue has been resolved now the GAS fees went down. I am adding a summary below in case someone else encounters the same issue:
While confirmed transactions were visible, two pending transactions (pending for 6 days now) were not visible at Trezor Suite. Meanwhile I could see them at Etherscan as pending.
Initially Trezor Suite was not allowing me to initiate any other transaction, I can’t remember the exact error message but it was something like “the address is different”. This is also resolved today.
