Roon App Crashes on iPhone Pro 12 Upon Launching

I am running Roon Nucleus B. When I launch the Roon App on my iPhone 12 Pro, it immediately crashes upon launch. It does not even stay open for a full second. I also tried the App on an iPhone 8 same response. Also there are issues with the App on my iPad Pro which is unable to access to Sonos devises when I attempt to control the various zones. The only OS that gives me full access is on my Mac Pro. I look forward to clear steps for solving. Note I re-installed the App and also shut down the devises and re-installed to see if that would help which it unfortunately did not. Thx, B
