There was here a discussion about this topic but then it was deleted which is very annoying.
For some reason I ended with 2 plugins: one is version 8.1 and the second one is version 15 ( the latest). I did not install two plugins but it happened after one of the updates. the latest version is not active and I am still using version 8.1 as there was some customisation done.
I deactivated the old plugin and activated the new one on my staging website but obviously, all the CSS is not there, also on the staging website I don’t have a pro version, so I can’t test some important fields how they work and how they will look if I import the CSS.
I sent an email to Najeeb a couple of weeks ago asking for customisation and also called but since then no answer.
Sorry for this, well can you please send email again to firstname.lastname@example.org and share what customization you had in older version so we can see what we can do to make these changes in latest version.
