@Carole878. You are correct its a glitch. I reported this issue 23 hours ago to ABB Support (AEST). It has now gone from only one of my listings not appearing using a default no date or Im flexible enquiry to now (as of 15 mins ago checking again) ALL of my listings wont show without dates. My calendars are all open for next few months with plenty of availability.
Now trying to work out how most of others are still showing (31 out of usual 55 in a small town search). I am wondering if IB is at play as I dont use IB? Is not SH either.
Will update you when they get back to me but clearly there are a lot of us impacted. Its still summer here as well 😞
