Really? So many threads, support tickets and ideaboard items are there for these already!
Bubble just doesn’t listen and wants to just cash on the customers who have got “locked in”.
So many things on WU tracking, debugging, logs analysis (Ref this idea), WU optimisations are pending (Ref this post) to be fixed. So many questions on how WUs work are also unanswered! (Ref this post)
And these are just a few of my own posts that I could quickly dig in. There are many other posts (and bug reports which you don’t give us any way to share or link with others) which are on it. Bubble just seems to portray as if all is well.
