Escape ropes are a money sink which are important for MMOs like PRO.
Here is a similiar suggestion which was denied in the past:

+1 to increase the drop rate from bosses or add more bosses which can drop it.
As suggestion for the future maybe there could be a new excavation site at the Crater Town area which could have Twin Dragon Orbs as rare drop.
From what I know the main issue is actually from apples side rather than from PRO itself because of apples limiting rules for third-party applications.
Are you able to login to the forum with that username and password?
Did you possibly use any special characters on your password? If yes make sure to reset it to a password which only contains normal letters and numbers and try to login again.

It is coded as you can check here: https://pokemonrevolution.net/forum/topic/28126-list-of-broken-moves-abilities-in-pro/
What made you think it is not coded though?
IV locked rerolls are only rewarded from special occasions like from quests during seasonal events, PvP Ladder Tournament, PvP Summer Tournament and other special mini-events.
