Yup I can confirm this seems to be case. I’ve flown every day (almost) sometimes twice or three times a day for the last two ½ years. Usually around 1-2 hours per session. Based on that I should have somewhere around 3000 hours but only have 1700ish. Plus my logbook stopped logging hours in March. So three months no hours added to the book.
In 2023 it’s sad that a simple logbook cannot be correctly updated and logged.
