Extremely slow execution of an external dependency function

Hello MongoDB, did you get improvements on this executions times? I am about to integrate payments through Stripe into my app, and I can’t loose sales. If I loose sync to Algolia, I can recover later, but that is not feasible for sales.

I use Realm Password Auth for my app, so relying on Realm Functions is wanted, where I can check the auth state. So having Stripe into the Realm Function is very very needed.

Thanks, I want to rely as much as possible into the MongoDb platform.
