The scan or the send is not working
Almost always the property WiFi. What to tell your cleaner, in one message.
What it is
Guest WiFi that shows a sign-in page lets a phone connect without reaching the internet, which is the most common cause by far. After about twenty seconds of sending, the page says so: if this WiFi has no internet, turn WiFi off for a moment.
How it helps
Turning WiFi off and using cell data fixes it immediately. Tell a new cleaner up front so the first scan is not the one that goes wrong.
What to be aware of
A send on bad signal is not lost. Restock accepts the report and keeps retrying while the page is open, and an interrupted send resumes when the page comes back.
If the code itself fails, check that the Card ID on the wall matches the current code in your dashboard, and restore the old code if the new card is not hung yet.
A cleaner can save the page to their home screen and open it like an app, which removes the scan and the lighting in a dim closet with it.
