Pre-Update Check for Joomla ‎4.2.2 - Extensions Pre-Update Check fails

Hi,

All the plugins included in HikaShop are compatible with Joomla 4, regardless of what the pre-update check system says.
Also, it shouldn't say that they are not compatible but that they are "pontentially not compatible". Basically, the check system doesn't know. It just saw code that doesn't work in Joomla 4 in there (and that's normal since HikaShop still supports Joomla 3 with the same files, we just have checks to run either the J3 or the J4 code based on your current version of Joomla).
So in short, you can just ignore these for plugins and modules included in HikaShop.
For plugins made for HikaShop but not included in HikaShop, it depends who made them. For plugins made by us, like the PDF invoice plugin, if you have the latest version on the website, it will work fine on Joomla 4, but these need to be updated manually.
