How can I disable all autocorrect in Collabora Online Calc?

The writer assisting features are frustrating for me in Calc, since I often need inputs exactly as I type them without changes. I disabled spell checking, but Collabora is still enforcing grammar corrections such as capitalizing the first letter after a period. I also found a Language setting in the Spelling menu and set it to “None”, which also seemed to do nothing. Online documentation suggests there should be a “Tools > AutoInput” or “Tools > Autocorrect” menu, but neither of those exist in my version, and those options don’t appear anywhere I can find. Some help would be appreciated.

I’m using version 26.04.1.4

I checked this, yes the option does not appear to be available in Calc, I imagine this is already on a list of things to port to the Online UI.

In “Issues”, “Turn-Off Auto-Capitalization on iOS #14889” looks related. It may need to be raised as a new feature request on Issues. I don’t know.
