If the Coinbase app freezes on the splash screen or crashes right after opening, start with the basics: force-close it, clear the cache (Android: Settings → Apps → Coinbase → Clear Cache), and relaunch. If that doesn't help, check whether a newer version is available — outdated builds often break after backend updates. Reinstalling usually fixes persistent crashes.
A failed login is almost always one of three things: wrong credentials, a time-sync issue breaking your authenticator app, or a session conflict from multiple devices. If your 2FA codes aren't accepted, open your authenticator and make sure the device clock is set to automatic. Even a 30-second drift kills TOTP codes. Try logging in from a private browser window to rule out a corrupted session cookie.
Some transactions sit in 'pending' for longer than expected. This happens when network fees were set too low during congestion. On Coinbase, you don't set gas manually for custodial wallets — but if you're using Coinbase Wallet (self-custody), you can speed up the transaction by replacing it with a higher fee. For custodial accounts, there's no manual fix; you wait for the network to clear.
If balances look wrong or recent trades aren't showing, it's usually a sync delay on the client side. Pull down to refresh on mobile or do a hard reload on desktop (Ctrl+Shift+R). If the issue persists across devices, the platform itself may be experiencing elevated load — check your email for any status notifications from the service.
A sluggish dashboard during market volatility is common — high trading volume puts real pressure on the infrastructure. Switching from Wi-Fi to mobile data (or vice versa) sometimes helps if the bottleneck is on your network side. Running a quick ping test to api.coinbase.com tells you whether the delay is local or upstream.
