If you encounter an issue where Trezor Wallet gets stuck on a screen that reads “Loading”, please try clearing your browser’s cache and refresh the page.
Also, if you are using VPN, certain advanced Firewall or Antivirus settings, browser extensions (AdBlock, Privacy Badger etc.), or some cryptocurrency apps such as Geth or MetaMask, try disabling them. It is possible that some of these are clashing with Trezor Wallet.
If none of the above helped, please contact our customer support: customer support contact form.
