Dont support my tablette anymore (Acer A3-A30)

Hello Guys. 

Workflowy is a Wonderfull tool but since yesterday, it seems that it Doesn't work well on my Tablette (Acer A3-A30). 

It Doesn't let me expend any of my bullet point, and it bug when I try to add à New line (it Doesn't even allow me to write something in it). 

I used it the past few days, and didn't had any kind of problem so far. 

It would be great if you can look into it, and let me know if it can be resolve or not. 

Thanks for your time Team Workflowy, and thanks you for that useful application that you created.
