App tells me to update the app when trying to add a speaker

I have 2 speakers: a Roam 2 and a Roam SL.

I successfully added both of them, only to notice that they were set up as 2 different systems. I factory reset my Roam SL, but when trying to add my Roam SL to the same system as my Roam 2, it tells me that I need to update the app, and when I click on the “Update Sonos App” button, it brings me to my browser to a page to update the Beta Controller App.

I was a beta tester for the Roam 2 speaker, but I changed phone since then (from Galaxy S22 to a Pixel 9) in case it’s relevant.

Could uninstalling the app, and re-install it fix the problem?
