Hello, Clau8826,
For Improved Asset Loading and Improved CSS Loading we recommend selecting – Inactive.
About others, we did not get bug reports.
You can test these features on your local site or staging as we cannot test everything taking into account our time for developing new things and improving existing ones. If you do the test, please provide us with feedback so that we can understand what to provide as answers to other similar questions from customers.
Kind Regards,
8theme team
