Anova Oven App Freezing/Won't Open

Hi Everyone!

I’ve found one of the best features of my APO is the App - but lately (only had the APO for a few weeks) the app becomes unresponsive mid cook and exiting the app means I can never open it again.
I’ve had to uninstall and reinstall the app multiple times, often twice in 1 day just to get through a cook.
Has anyone else experienced the same?
I have a Samsung GS8 & app version is latest available on google play store. I’ll raise a separate support request as well.

Could this be a weak wi-fi problem? Just guessing here.
