Ledger Networks and Apps | Support Check, Account View, and Device Screen
Ledger network and app support should be checked through three visible layers: the app entry, the account view, and the device screen. This keeps the question practical without turning a support list into a broad promise about every network or app.

Direct Answer: Check Network, App, and Account View Together
A supported network or app should make sense across the app entry, the visible account view, and the device prompt. If one layer is unclear, pause and confirm that layer before adding more accounts or changing settings.
Use the App Entry to Confirm the Network
The app entry is where users usually see available account paths and network labels. For a broader support overview, compare the question with which Ledger supports across apps and networks.
Use the Device Screen for the Final Prompt
The device screen should match the action being reviewed. When the question is about whether the environment itself is ready, Ledger network requirement check gives a clean way to separate app access from device confirmation.
Keep a Record Before Adding a New Account
Before adding a new account view, record the app entry, network label, device model, and screen prompt. If the issue is compatibility rather than network support, supported OS versions and Ledger Wallet compatibility is the better reference point.
A useful record does not include recovery phrase words or PIN digits. It only states which entry was used, what the account view showed, what the device screen displayed, and whether the support check was complete.
