The login code email doesn't arrive
Wait 1–2 minutes. Then check Spam, Junk, Promotions and Updates folders. Search your mailbox for "HeyDrop".
Check the email address shown on the Check your inbox screen ("Enter the code we sent you to …"). If there's a typo, tap the back arrow, fix the address and continue again.
Tap Send new code. The button becomes active again after about 15 seconds. Always use the newest code; older codes stop working.
Company email? Some corporate mail filters hold external emails for a few minutes. Wait, or ask your IT team to allow emails from heydrop.app.
Tap Open Email to jump straight to your mail app.
"Invalid code. Please try again or send new code"
The code was mistyped, already used, or replaced by a newer one. Tap Send new code and enter the latest 6 digits. Don't reuse a code from an earlier email.
"Could not sign in with Apple" / "Could not sign in with Google"
This appears when the Apple or Google sign-in window is closed before finishing. Tap the button again and complete the sign-in. If it keeps failing, check your internet connection, update iOS and the HeyDrop app, and try again.
"We couldn't load your data"
Your account signed in but the app couldn't download your cards.
Check your internet connection (try switching between Wi-Fi and mobile data).
Close HeyDrop completely and open it again.
Make sure you have the latest version of HeyDrop from the App Store.
I see the onboarding again / my cards disappeared
You probably signed in with a different method than the one you first used, which created a new empty account. See "Signing in, login methods and 'my cards are gone'".
The app shows "Upgrade" even though I paid
See "I paid but Pro features are still locked".
Mail, WhatsApp or other apps won't open from HeyDrop
Messages like "Could not open mail app." mean the app isn't installed or set up on your phone. Install or sign in to that app, or use Share Card → Share or Copy link instead.
Changes to my card don't show
Your card updates online immediately after you save. If the person you shared with still sees old details:
Web card / QR code: ask them to refresh the page. The QR code and link never change, even when you edit the card.
Apple Wallet: open Wallet in HeyDrop and tap Update in Apple Wallet to replace the pass on your phone.
Contacts saved earlier: a contact someone already saved to their phone is a copy and won't update. They need to save your card again.
Something else isn't working
Update HeyDrop to the latest version from the App Store and restart your phone. Most display glitches go away after an update and restart.
