Works Fine on my iPhone 11 for a few things
I just use the 311 app mostly to look at the “suspended parking” days but submitted a request to replace street parking signs after a bike thief removed the sign and slid both of our bikes up and over the street sign post - bye bikes. Took 6 months for them to replace the signs, but still worth the effort to report because before you know it, 6 months flies by quick.
