after downloading and installing 26.01 my new messgaes are all disappearin

I installed 26.01 yesterday. This morning an important message from hospital giving me the code for the box to retrieve my medication was gone. I always keep all my messages.

I phoned the hospital, got a refreshed message and new code and 2 hrs later it is gone again!

Now the message box to provide more detail displays below it that I have to include text. This is text!

this an iPhone 12 Pro, was very happy but this is a no go as my health because of this stupid bug can cause me great problems.
