Spelling check/correction does not work

On my samsung galaxy note 9, despite being active, the spelling correction does not work, either with the swiftkey keyboard or with the gboard.
I purposely wrote two words with gross errors and onlyoffice did not detect them.
In addition, on the keyboards, the word suggestions do not appear, unlike what happens in other similar applications.
Is this a bug, or can I solve this?
Thanks.

Please clarify the version of the app and how exactly you open a file (locally or from cloud).
