After I asked here https://www.joomshaper.com/forum/question/23380 for the update, I got a RC version of the update from Paul, I installed it on a copy of the affected website and I replayed all the problems I had with the 4.0.8 update - I can say - no change!
Not a single problem that was caused by the 4.0.8 update has been solved with the RC update - no one is reporting anymore either - I can write as much as I want - thanks guys!
Here also does nothing more https://www.joomshaper.com/forum/question/23128, as if Ofi had hung up his job or after answering a question thinks that is already enough.
I don't understand this as support , for this I don't waste my time to describe my problems with the update 4.0.8 and also not again to check everything again after the RC update installation if there are any changes. If you don't have any solutions guys, please express that - then I don't need to wait for response.
