The creator can pick moderators to help run the group. Member tags, slow mode, agreeing to the rules first, subgroup categories and announcement subgroups are Pro features, based on whether the main group's creator has Pro.

When the main group's creator has Pro, the main group and all its subgroups get advanced group management: up to 10 moderators (2 on the free plan), member tags and @tags, slow mode, new members agreeing to the rules before posting, subgroup categories and announcement subgroups.
Still free: the welcome message and rules text, muting, threads and no-install web links.
If the main group's creator no longer has Pro, settings are kept but paused: slow mode, agreeing to the rules and announcement subgroups stop applying; tags stay but can't be @mentioned; moderators beyond 2 keep the title, but only the first 2 appointed can manage. Everything comes back when Pro is back.
When the main group's creator taps a "Pro" item, the 24h Pro page opens. Moderators and other members see "Available after the group creator upgrades to Pro".
