Opening up the picker for sending a picture was notably slow. Approximately a three second count from pressing the button to having the pictures available to choose from. Then similar occasional lags throughout the process (e.g. hitting "back" from a picture to return to the library and select a second picture). By contrast, Telegram has a quick selection of the last few pictures available immediately, and the general picker opens quicker if you request it -- maybe because it's using the stock iOS picker rather than the custom one Signal implements? Since sending a picture to a contact was a super common action of mine, this was incredibly frustrating. Signal also had notification issues if I was running the desktop client at the same time. It'd sometimes clear notifications from my phone before I'd actually read them in either location.
