Dashboard Navigation Issues 2.3.9.166 - both iPhone and Safari Browser

I have a C-8 with 2.3.9.166 and my iPhone is an iPhone X with 16.7.9 (most up to date for an X).

I was in Safari and went go to one dashboard and then with the navigation button went to a 2nd dashboard. I then tried to use the <- to go to back to the first dashboard and I got the "connecting" message in the upper right of my screen:

I was able to repeat this a few times, (which is how I got the screenshot).

And then I got the "connected" message. (I wasn't fast enough to get that screenshot). and it wasn't working.

After a few minutes I went back and tried it again, and it is now working.

Also, on my iPhone I only have the right arrow, <-, not the nav button. I don't have the navigation button at all.
