Decryption changes v9.0.4

We upgraded the firewall to v9.0.4 from 8.1.11h2 this weekend and came in to our hosted exchange / outlook profiles failing to load. I added the mail host server in the do not decrypt policy and a percentage of the users reported services normal. It was not until I disabled decryption completely until the entire network started working consistently. Has anybody had any new decryption issues post upgrade?

The only thing that should have changed is that 9.0 would be performing decryption on HTTP/2 connections; that's really easy to disable in a test decryption profile by selecting the Strip ALPN option and applying it to a test client and seeing if that works properly.
