Hi,
I've been working with PB3 for a number of years and now with version 4. I can't say it's an improvement there are a lot of errors it's completely disconnected from the Joomla CMS so you first have to log in to Joomla again and then you can you can't save the work and have to redo everything again.
I went back to the old PB version 3.8.9. it worked flawlessly.
I expect from Joomshaper that these errors will be fixed and then, only when all major errors have been fixed, I will receive a good version. This is really unacceptable, paying for an unfinished version that was released way too early.
Regards,
Bert
