Marking lessons taught

After a lesson's time has passed, it says Not marked yet. Choose Mark taught, No-show or Cancelled or other. Several at once? Use Finished, not marked yet on Today.

Marking a lesson taught adds it to what the family owes (unless their credit covers it). Swimvity then asks how it was paid (Paid now, Use credit or Payment pending), but you can ignore the question. No-shows aren't charged unless you add an agreed fee.
