I fear the problem is not solved
I have the problem not only there but in all the pagebuildersettings. I tried to add a license in a new website and had the same problems. Sometimes later (a day) it works.
Same problem when i try to save Infos in SPPagebulder settings like OpenAIAPI-Key or anything else. I save- get the massage "Settign saved successfully" and even when i go to "Color Library" the and return to "option" all entered data is lost. Sometimes after 50+ tries it works. Since noone else seams to have that problem, its obviously not a general SPPB problem. Any idea where to look?
