If the app refuses to sign in, work through this concise checklist to get back in within minutes.
Update the app and operating system; outdated builds often block authentication.
Force‑quit and clear the app cache or browser cookies, then retry the sign‑in flow.
Use the „forgot password” flow to reset credentials and pick a strong, unique password.
Check network: toggle Wi‑Fi/mobile data and disable VPNs that change region.
Verify two‑factor codes and device time; sync clock if codes show invalid.
Record exact error text and time, take a screenshot, then contact support if the problem persists.
Security tip: enable biometric unlock, monitor recent activity, and never share credentials. Takeaway: follow this checklist before contacting customer service — most login issues resolve quickly.
