Threads text attachments: going past 500 characters

When 500 characters isn’t enough, Threads lets you attach a block of text of up to about 10,000 characters to a post. The post itself keeps its 500-character limit; readers tap the attachment to read the rest. The feature has been rolling out gradually, so you may not see it on every account yet.
