toolbar buttons not showing sometimes after upgraded to iPadOS26.

(Sorry if this is not the right place to post...)

I upgraded my iPad / macOS to 26 yesterday. Soon, I noticed that the two buttons in the toolbar would sometimes not appear:

Note that they should be visible at all times.

I played a little more to see if there was any pattern, but I could not find any. Has anyone experienced something similar...? Is this an iPadOS26 bug? (I haven't checked with an iPhone yet.)

Thanks.
