there are a few potential reasons why Trezor Suite might be showing a zero balance:

1. Incorrect wallet access: You may be accessing the wrong wallet, especially if you used a hidden wallet feature. The XPUB (extended public key) for the wallet showing zero balance may be different from the one with your actual funds.
2. Hidden wallet password: If you used a hidden wallet feature with a password, you need to enter that password to access the correct wallet and see your balance.
3. Caching or synchronization issues: Sometimes clearing the cache or allowing the wallet to resynchronize can resolve balance discrepancies.
4. Browser version compatibility: Ensure you're using an up-to-date browser version compatible with Trezor Suite.
5. Mobile web version limitations: The mobile web version of Trezor Suite may not remember wallet information after disconnecting, unlike the desktop software version.

To troubleshoot:

1. Double-check that you're accessing the correct wallet, especially if you've used hidden wallets.
2. If you used a hidden wallet, try entering the password you may have set for it.
3. Verify the XPUB of the wallet showing zero balance against the XPUB of the wallet where you expect to see funds.
4. Try using the desktop version of Trezor Suite or the older wallet version at wallet.trezor.io to see if your balance appears correctly there.
5. Ensure your browser and Trezor Suite are up to date.

If none of these steps resolve the issue, it's advisable to contact Trezor support for further assistance, as a persistent zero balance could indicate a more serious problem.
