Loading circle on mobile device

Hi folks,
I noticed a spinning circle on mobiles devices (iPhone, tried Safari and Chrome), I'm attaching a screenshot of it.
Any ideas what that might be?

This sounds like old/incomplete css bring loaded. does it also happen on https://pretix.eu/demo/?style=list for your?

if yes, what browser and os are your using?

if no, can you share the URL to where it happens?

We have csp_additional_header: https://docs.pretix.eu/en/latest/admin/config.html#pretix-settings

@raphaelm thank you. The syntax in the documentation isn't obvious for me. Is that a correct example below?
[pretix]
csp_additional_header=script-src https://mycdn.com

@raphaelm would be grateful for your confirmation

Yes, that looks right. You could even add more instructions, it just has to be a valid CSP-Header string as described e.g. at https://content-security-policy.com/

Unfortunately this doesn't make any difference, I tried various settings.
