I worked on a Bubble app that definitely hit the limits of how big apps should be. The work flow box things still give me nightmares. It's very hard to figure out the order things were executing, and we had to resort to A LOT of JavaScript blocks to break out of the normal workflow to get features working that weren't achievable with the built-in tools. If felt like there was a missing level of abstraction - everything was too intertwined. Making changes to anything becomes harrowing once the app becomes large - it was slow, and you don't know which UI elements are being accessed by any blocks - so it's really easy to break things without realizing. And the undo system gives you no visual clue as to what is being undo-d if it was in a different view. It was the most fragile system I've worked on. However, many of those issues could be fixed, improved, or redesigned. If you were doing "regular" use-case stuff it was... fun! Our designer could get in and implement/test things really easily. My gut feeling is that there could be system that scales well - but the escape hatches need to be reliable when you hit the edges.
