App on Shelly WallDisplay XL quits Dashboard seemingly randomly after a few hours

**Android version(s):**
No idea what Shelly's Wall Display XL or X2i are running

**Device model(s):**
Shelly Wall Display XL, Firmware versions 2.6.0 stable and 2.6.1 stable

**Home Assistant version:**
App Version 2026.5.1

**Last working Home Assistant release (if known):**
Former firmware versions of the Shelly Wall Display did not run the Android App - had Zero issues with HA dashboards prior to updating the Shelly Wall Display XL device from Firmware 2.5.8 to 2.6.0

**Description of problem, include YAML if issue is related to notifications:**
I run different dashboards on 4 different Shelly Wall Displays XL in different rooms. I run those dashboard with "kiosk-mode" from HACS. Everything worked fine and stable before upgrading to Firmware 2.6.0 / 2.6.1 of the Shelly Firmware. Now the Wall Displays quit the Dashboard they are in and return to the default Home Assistant Main Menu after a certain period of time, not more than a few hours so that I have to start the correct dashboard several times a day.

I opened a ticket with Shelly, but they do not take responsibility- they simply said that this is a fault of the Home Assistant App. I actually am pretty disappointed by Shelly playing the "blame the other guys" here. I am pretty frustrated that a once perfectly working dashboard solution in my home now is a pretty bad experience.

**Additional information:**
Am I missing something? Is there an app setting that helps with the situation? If not, can the Home Assistant teams and Shelly please talk to each other to get this resolved? Again, I am pretty frustrated with the situation and particularly the "oh, it's not us, it's the other party" stance.

Can you help?
