How long can I keep my SCOBY in the starter before the next brew?

Hey I'm kinda new to this whole kombucha thing and even after doing some research I've found really different answers.. got my SCOBY (there are like 3 of them actually) chilling in about 700 ml of starter tea for roughly a month. My first two brews gave me a bit more liquid than expected lol it was around like 3.5 L total and it's just me drinking it. Right now, I have about 1 L of hibiscus & rose kombucha and a bit less than half a liter of plain one. I read that a SCOBY can survive for several months in starter tea even if you're not brewing immediately. But the problem is... Some sources say 2 months is safe, others (including some AI answers lol) suggest up to 6-7 months.. So my questions are:

1. How long is it actually safe to let the SCOBY stay in starter tea before starting the next brew? Max.

2. Does letting it sit longer affect the flavor, aroma or acidity of future batches?

Any tips or advice would be super appreciated! ♡
