Scheduling not being following from 01/01/2021

Describe the bug

The collection pattern is every two weeks, beginning 14/12/2020 and running until 29/11/2021, with three exceptions during the year for bank holidays.

It should be 14/12/20, 28/12/20, 11/01/21, 25/01/21 and so on, every two weeks (apart from the bank holidays). No matter what changes I’ve tried it just keeps switching from 04/01/21 and I can’t work out what I’m doing wrong. I’ve rebooted multiple times, just in case that might help but no difference. Another user has the same issue, following the roll over to the new calendar year.

Hopefully I’ve done this properly and not missed anything, if you need any more information or for me to test things please let me know.

Thanks!

Ok, you are right. Every n weels works the same way as odd weeks, I forgot. Please use EVERY-N-DAYS. There you can set-up a starting date. And for 2 weeks select period 14 (14 days).

Thanks for the help, all sorted now. I’ll stick with every-n-days from now on, as that seemed to fit all scenarios.
