NoSuchElementException while trying to click an element but element is clicked

Issues/Bugs
1

Hi, I just started using appium and I decided to make small scripts that make and send photos on Snapchat.
I am running it locally on Xiaomi mi5.

My code crashes 50% of the time, and always from NoSuchElementException.
The weird thing is the code throws an exception when I try to click an element, but I can see that on my phone element is clicked.
I am sure that selectors are valid.

Simple version of my code

snap = Device()
snap.make_photo() <- // this throws NoSuchElementException
snap.press_send_button()

Versions

App version: 1.21.0
Electron: 7.2.4
Node.js: 12.8.1
Os: Ubuntu 21.04

Full source code

class Device:
    def __init__(self):
        desired_caps = dict(
            platformName="Android",
            automationName="uiautomator2",
            appPackage="com.snapchat.android",
            appActivity="LandingPageActivity",
            noReset=True,
        )

        self.driver = webdriver.Remote("http://localhost:4723/wd/hub", desired_caps)
        self.driver.implicitly_wait(15)

    def _rselect(self, r_id):
        return self.driver.find_element_by_xpath(f'//*[@resource-id="{r_id}"]')

    def _rclick(self, r_id):
        self._rselect(r_id).click()

    def make_photo(self):
        self._rclick("com.snapchat.android:id/camera_capture_button")

    def press_send_button(self):
        self._rclick("com.snapchat.android:id/send_btn_layout")

Screen is probably in transition 50% of the time, so you are trying to click the button before screen is rendered. Try adding implicit waits to your code:
