I’ve had the duty screen freeze on me every now and again; something that is usually fixed by manually forcing the game to close and restarting it, but I havn’t had the issue of missing text… And I have to admit I’m a bit surprised that uninstalling and reinstalling the game entirely didn’t fix that. Because that would imply it’s something hardcoded, and not just a ‘hiccup’.
In this case you would usually be asked about the specs of your phone. Does it meet the minimum requirements specified for the game to run?
Also, the more RAM available on your phone the better. If you’re running low on storage it can put a strain on these things.
And then, finally, multiple windows. I, personally, don’t have issue with having multiple apps up while playing because I have terrible habits, but this can adversely affect other players during gameplay and is usually another thing that is commonly recommended Not To Do.
I feel like this is a bug that has happened before, albeit a few updates ago. Or at least something similar. It might be you have a particularly stubborn case of it as I could have sworn it was fixed.
If none of this is an issue, you might just have to wait for Mario to get back to you. Which, again, with the delay might take a bit.
Of course if anyone else here has had a similar experience and knows a possible solution, I do welcome their input!
