I just found sth so I'm creating a sticky for this for documentation.
If you find something different please write them here for documentation!

This is tested on MacOS I need to confirm these on Win, too.
Seeding of the RNG of daily challenge seems faulty: If month doesnt change, then 364 days later has the exact same layout.

For Example:
07/02/2020 and 07/02/2019 has exact same layout and 01/02/2025 has exact same layout Because 364 * 5. BUT 31/01/2026 does not have exact same layout.

This means After someone tests 365 days of a single year we only need to check 12 other ones in each year. Searching for a seed got easier!

Another finding:
iOS and MacOS has the same seeding.
I'm not sure but Android and Windows has same seeding too.
But MacOs and Windows are different.

Can you explain everithing?
