Why didn't the queuer get the prompt to enter their mobile number?
When the SMS prompt does and doesn't appear.
When SMS is enabled, the phone-number prompt is available when the number of people ahead of the queuer is at least the configured SMS threshold. If only a few people were already ahead when they joined (fewer than the threshold), they’re past the point where SMS is useful, so the prompt is skipped.
When SMS is turned off for the queue, neither the phone-number prompt nor the bell icon appears.
How to find out where the threshold is
Section titled “How to find out where the threshold is”In Flowby admin, open the queue and look at the SMS notification settings. The threshold can be disabled, set to notify when it is the queuer’s turn, set to notify when the queuer is first in line, or set to notify when the queuer has one person ahead.
What the queuer can still do
Section titled “What the queuer can still do”If SMS is enabled, the queuer can tap the bell icon at the top right of their queue view to check whether they can still sign up for an SMS.
