I received Rebyota 6-4-2024. I don't recall any side effects. There has been some up and downs since then. A couple times I thought I had relapsed. But after testing I was Negative.
My BM's have been different than before the Treatment-but it still beats having Cdiff!
I wish you well and hope it works well for you.

PS- I had 2 regular FMT Treatments by Colonoscopy route previous time Rebyota.
One was in 2023. It did well and lasted 13 months.
The Second one , on 4-15 24 (same GI DR, used Open Biome on both), for whatever reason was a failure from the start.
