iPhone 12 Pro Max memory issues after update 26.6, update 27.0.1?

Hello. I have a iPhone 12 Pro Max, and I just want to know if it’s ok to download the new software 27.0.1

It’s currently running the 26.6. With that software my phone lost most of its memory. It took several months to get it back on its own. I only had 25 GB. Now it’s back to 200 GB.
