iOS application logging out

Hi,I'm just wondering if anyone else has had issues with their apps arbitrarily logging themselves out (silently)? Is there a way to make sure I get notified if the app logs itself out in the future?I've missed a number of deliveries because it had silently failed - and effectively called someone a liar who'd insisted their delivery driver had used the doorbell.Needless to say I'm unhappy with Ring just now.Thanks,Dave
