Troubleshooting

Sign in and link

The code does not arrive in my email.

• Check the spam or promotions folder.
• Wait a minute and tap “Resend code” (on the web, “Send another code”).
• On the tablet, check that you chose “Yammbo POS (restaurants or shops)” under “Where is your account?”
• The code expires after 30 minutes.

“Your account has no business you can link”. Finish the wizard at pos.yammbo.com or create the business from the tablet with “Create account”.

The “Link device” button is turned off. An active employee with the Owner role is missing. Create one in Team > POS employees.

“The code expired. Generate a new one.” The dashboard code lasts 5 minutes and is used once. Generate another one in Devices.

“Wrong PIN” or “Too many attempts”. Wait the seconds it indicates and try again. If the employee forgot their PIN, the owner changes it in Team > POS employees (or in Staff on the tablet if it is not linked).

Taking payments

I cannot take payments.

• “Open a shift to charge”: open the shift in Shift. Each tablet needs its own.
• “No payment methods are active”: turn on at least one method in Settings > Payment methods.
• The fiscal invoice reached the end of its range or expired: update it in Settings > Fiscal invoice.
• “Register locked for lack of payment”: see Plan and billing.

“The phone number is not valid”. Enter the local number with all its digits or add the country code with +.

The receipt email does not arrive. The tablet has to be linked. Without internet, the email waits up to 24 hours and is then discarded.

It does not print

1. Tap “Print test” in Settings > Printers and hardware.
2. Bluetooth: the printer must be on and paired in Android’s Bluetooth settings.
3. Network: the tablet and the printer on the same Wi-Fi, and the right IP. Use “Detect equipment”.
4. USB: accept the USB permission that Android asks for when you connect it.
5. Check the paper width (58 or 80 mm) and that the printer is ESC/POS.
6. Each tablet has its own printers: if you changed tablets, set it up again.

Kitchen orders do not come out. On the kitchen printer check “Stations it prints” and that the product has its “Preparation station”.

Multiple tablets

“The other register runs another version of the app”. Update all the tablets to the same version. See Update the app.

The tablets do not share data. They must be on the same Wi-Fi. Some guest networks do not let devices see each other: use the main network.

I see alerts in “Conflicts between registers”. Review each one and tap “Mark as reviewed”. See Multiple tablets.

Online ordering

Online orders do not arrive.

• Online ordering must be turned on in Store and your plan must be Business (or be in the trial).
• The location needs a register with internet: without one the page stops accepting orders.
• On the tablet, in Settings > Location and devices > Online account, turn on the battery and notification permissions so Android does not put it to sleep.

“Your plan does not include online selling”. Switch to the Business plan in Billing.

Update

“The update failed”. Tap “Download from the browser” and install over it, without uninstalling.
