ACF Oembed Spotify links stopped working

I use field groups for my elementor post templates for years and everything has worked out fine… till the recent update.

One field I use is an “oembed” field in which I copy a Spotify link and then it will be displayed as this nice Spotify “widget” – on old posts this is working fine (see for example this blog article).

But unfortunately it stopped working for new blog articles. When I now try to insert a Spotify link the link will be displayed as text. (see for example this blog article).

All other (text) ACF fields are working fine…

Please help me how to fix this – I am working on this for days and have still no solution..

All the best and thank you so much for your time and effort!
