Apple Watch Ultra issues after watch OS 26.2 update

Ever since updating to watch OS 26.2 I have been having the following issues on my Apple Watch Ultra:

the messages app keeps disappearing. And even when it is listed, I often times can’t click on it. Sometimes it will be there, sometimes it won’t, sometimes it will be there and not working. Seems random.
on my runs, the elevation gain feature is not working. At first it was just incorrect but now it just isn’t showing any elevation gain total even though you can see the elevation chart
the current pace when I run is not correct. It seems like it’s weighing my arm swing more than the actual distance I’m traveling

I have reset my watch, checked the software is up to date on my watch and phone, logged out and in of my watch, turned it on and off several times a day, reset the calibration. Nothing has worked.

The watch also uses the movement of your arm to estimate the distance by the number of steps taken.

To rule out a software issue, erase the watch and pair it again, setting it up as a new device. You will only lose your created Watch faces and may have to activate the cards in your Wallet app again.

Also check your listed height in the Health App ->Body Measurements.

Then record an Outdoor Walk or Outdoor Run and calibrate the watch again, if needed.

if the watch is correctly set up it uses GPS for distance, and arms wings for steps.

Calibration is really only needed for steps or indoor running.

There is or was a problem with GPS on that watch.
