Official Q&A: VRC 2019-2020: Tower Takeover

I was told teams were prohibited from using scoring application on their mobile device at Worlds this year by the head referee in HS divisions. This is bizarre since nothing prohibits the use of mobile device other than prohibiting wireless communication:

<G7> ....Drive Team Members are not allowed to use any sort of communication devices during their Match. Devices with communication features turned off (e.g. a phone in airplane mode) are allowed.

Given the complexity of scoring for this game, my teams would like to know for sure if they will be permitted to use a scoring application during the game at qualifying events and at Worlds. If they are permitted to use scoring application on their mobile device, may they use a custom mobile scoring application as long as it meets the requirements of <G7> as excerpted above?

Thank you for your kind consideration!
