Write to support@kusahab.app with the shell you were working on, the tick the head was parked at, and what you expected. That is usually enough to find the cause.
A span is written only when it fits whole into the blank under the head. A 24 tick blank cannot take a 45 tick span, and the app will not cut the span to make it fit. The line under the title always names both numbers. Move the head to a longer blank, or pick a slower rate.
Because position on the ruler is absolute. Lifting a span turns its ticks into blank and the spans after it keep their own start ticks. That is the whole point of the machine: a blank stays where it was.
Whole seconds. A clip is rounded down, and anything under two seconds is refused rather than looped to fill space. A still uses the duration you pick from two to twelve seconds.
Sound was off when the span was laid, or the microphone was not available. The picture is unaffected and the span still takes its ticks. There is no transcript and no added voice track.
Picture spans only, packed from tick zero at the rate you choose for the new shell. Blanks are not copied. If a span does not fit, it and everything after it stay on the source and are listed with their own small picture under Ran off.
A shell that has been copied four times is worn. It still plays, writes, and accepts a punch, but it cannot be the source of another dub.
Open the drawer. If a purchase was verified but the ledger did not take it, a Check again card stays there until the credit is recorded. Nothing is charged twice.
On Pile, Lift this span saves one picture into Photos, and Share sends one picture through the system share sheet. Delete Account removes everything on the phone, including the remaining Ferrite.
