There's an issue where in the Features and Traits section of the dndbeyond character sheet the description reads: 

As an action, you can use Channel Divinity and present your holy symbol to restore up to 30 HP divided among any creatures within 30 ft. up to half a creature's HP max. You can’t use this feature on an undead or a construct.

The actual description of this ability says: 

This feature can restore a creature to no more than half of its hit point maximum. You can’t use this feature on an undead or a construct.

There's a large difference between saying "up to half a creature's HP Max" and "the feature can restore NO MORE THAN half of its hit point maximum". The former many take to mean if I have 60 HP max I can be healed FOR 30 with this ability, as opposed to the latter clearly stating that I can only be healed TO 30. 

Can we fix the description in the Features and Traits tooltip? 

This is one of those things where the full correct wording displays in the sidebar if you know to click on it to look. When we customize an item or spell there's a little red asterisk to tell us that something is different, but when DDB customizes/abridges wording of a feature, there's no such marking to indicate a change.

Absolutely! But I think a small change to the abbreviated wording to make clear the specifics are a quick fix, no? 

Well, I'll just say that this isn't the first time the issue with the abbreviated wording of this Channel Divinity has been raised.
