this is a job very poorly done. I just downloaded a TEMPLATE file just to find the same issue of outlined text and not being able to change it.
You really should mark those stocks as "text not editable", "outlined text" or at least make sure those files cannot be marked or named as template, because they just aren't.
Frustrating and upsetting to see this is an issue that keeps happening after 3,5 years of "passing it to my concerned team." Very concerned indeed it seems. I will think twice if I ever get a template from Adobe Stock again if this issue not fixed. This has never happened with any other stock platform I have purchased from.
