Runs slowly if at all – Flow: Sketch, Draw, Take Notes Review

I have a 2018 iPad Pro with plenty of storage space and this app just cannot run. It’s very frustrating as I don’t know why it would not work for me. I had a trial period but ended up not using it as every time I select a tool or try to change a color, the app takes at least five seconds to recognize the command and the transitions are very stuttery. I uninstalled, restarted the device, reinstalled several times but still the same issue. I really wanted to use this as I love the design and it seems very intuitive to use, but unfortunately it was not.
