Google Spaces has returned the larger character limitations
For those who still enjoy Spaces or are trying to make it work for something, this is good news.

Starting Text Threads with no Limits
Following a lot of feedback, we've removed the limit on new text threads in Spaces. Within the latest versions of the Spaces app on iOS and Android and on the Web, you've got (almost) no character count limits when starting a thread with text.
As always, please send us your ideas/issues using the Send Feedback menu item in the Spaces app as that's the best way to ensure we'll see it. Thanks~
