Players still get priority while a card with split second is on the stack; their options are just limited to mana abilities and certain special actions.

Wotc — March 19, 2021

Players may turn face-down creatures face up while a spell with split second is on the stack.

Wotc — March 19, 2021

Split second doesn't stop triggered abilities from triggering, such as that of Chalice of the Void. If one does, its controller puts it on the stack and chooses targets for it, if any. Those abilities will resolve as normal.

Wotc — March 19, 2021

Casting a spell with split second won't affect spells and abilities that are already on the stack.

Wotc — March 19, 2021

If the resolution of a triggered ability involves casting a spell, that spell can't be cast if a spell with split second is on the stack.

Wotc — March 19, 2021

After a spell with split second resolves (or otherwise leaves the stack), players may again cast spells and activate abilities before the next object on the stack resolves.

Wotc — March 19, 2021

A mana ability is an ability that produces mana, not an ability that costs mana.

Wotc — August 23, 2019

In a multiplayer game, if the controller of one of the objects leaves the game after Sudden Substitution resolves, the effect that gave them control of the spell or permanent expires. If the spell is still on the stack, the player who gains control of it this way can't choose new targets for it.

Wotc — August 23, 2019

If the target spell or the target creature is an illegal target as Sudden Substitution resolves, the exchange won't happen. If both targets are legal but are both controlled by the same player, the exchange won't happen.

Wotc — August 23, 2019

If the exchange doesn't happen but the spell is still a legal target, its controller may choose new targets for it.

Wotc — August 23, 2019

The noncreature spell is still on the stack after exchanging control, and the creature is still on the battlefield.

Wotc — August 23, 2019

If a permanent spell is exchanged this way, its new controller will control the permanent it becomes.

Wotc — August 23, 2019

The exchange lasts indefinitely. It doesn't expire for the spell if the creature changes zones or leaves the game, or vice versa.
