Hi,
I’m using Collabora Office on iPad. I want to set a custom default template.
Furthermore, I’ve noticed, it’s impossible to import document templates (.ott and .dotx).
I’m on the latest version on iOS (23.05.5.2)
Thanks for helping me!

Can I ask why/how you were thinking of using templates (OTT+DOTX) on iOS?
