If I take Atywia Daily tablets every day but at different times (e.g. once at 9, on the following days 12, 14, 15) is the effectiveness of the tablets reduced?

Yes, if you regularly take Atywia Daily at different times, its effectiveness may be reduced and irregular mid-cycle spotting may occur while taking active tablets. Ideally, the delay in taking the tablet should be no more than 30 minutes. Of course, there may be occasional delays in taking the tablet for up to 12 hours, but this situation cannot happen every day. The decision to take the tablet after is entirely up to you. However, it seems that taking birth control pills in a way that may not provide you with protection against pregnancy is simply pointless - the product does not fulfill its purpose. Contraception should be taken correctly, or not at all - otherwise you still have to deal with the decision to take the pill after, which would be the same if you did not take contraception at all. It is therefore necessary to consider whether it is justified to use contraceptive pills at all in such a situation.
