A. First, check your transaction history within the app to verify if the funds or shares were indeed missing. If you find discrepancies, take screenshots of your transaction history and any relevant notifications. Then, log out and back into your account to see if the issue resolves itself.
B. If the issue persists, try uninstalling and reinstalling the app to refresh your account data. If the funds are still missing, document your findings and prepare to contact customer support with your evidence.
