I just recently began using Bubble and am almost ready to upgrade accounts. So, I’m not sure if this would even be useful or at least provide a workaround. Does the “Dedicated” environment look or behave similar to the Bubble hosted apps?
Something I did to “protect” me from myself during a major change I was doing was to clone the project. Would something like that work where you clone your current app - essentially create a QA_[AppName] then upgrade the Bubble version and run your Test Sequences on it?
Not even sure if that is possible in your environment but thought I’d at least suggest an idea.
