After upgrading the system to Home Assistant 0.109.3 the group file is not working anymore

Hi,
After upgrading the system to the latest HA version I’m receiving the following error:
“Invalid config for [group]: [view] is an invalid option for [group]. Check: group->group->default_view->view.”
Since I don’t understand where the issue is, I would really appreciate for your help.
Many thanks.

The groups.yaml file content is:

Did you jump a few versions?

view and control were deprecated for HA in 0.105.x - release notes - the notes advise it was planned for removal in 0.107.x.

…and they were indeed removed in 107.

@fchiari it’s a good idea to read the release notes before upgrading, especially if you’re going to update a few versions at a time.

Thanks, unfortunately I read the last release notes but not the previous one and then I lost the deprecated list of functions. Sorry for that.
In any case I have to switch to use the full Lovelace UI now. It is better.
Thanks again.
