Southern Rail advance Singles/lack thereof

[lilygsx]

I regularly purchase singles from my local station (Bognor Regis) to London Victoria to save money as the return works out relatively pricey to do regularly.
I use the advanced singles and try to book them as soon as they become released - which is normally around 10-12ish weeks from travel. But it seems like there are no released advance single tickets after the 17th may.
Is it just that this is taking any longer for no particular reason? Should I just be patient? Or is there some kind of longer term/more complicated reason for this?

First time posting and while I am not necessarily clueless when it comes to the railways (especially in my area) the nuances of the advance single system can be a bit confusing at times. Thanks in advance for any responses

The summer timetable change is the 18th May, that can affect the booking horizon.

The National Rail Enquiries page certainly agrees that Southern is only selling Advances up to the 17th May:

• Monday to Friday service: 16 May

Latest time of reservation​

Advance tickets are available up to 18:00 the day before travel.

Notes​

Southern do not offer seat reservations but have quota controlled advance purchase products.

For Saturdays and Sundays, advance fares for Southern services will be released approximately seven days after the amended timetable has been uploaded to journey planners.

Ah, yes that would make sense - I'd seen that part on the national rail page but hadn't managed to put two and two together RE timetable change.

Thanks v much.
