Experiencing UI issues with AJO? What are your process workarounds to avoid

My team (5+ people) has been experiencing issues with copying a journey and it causing an error. So it's not just one user with a connection issue.    We have been working on a journey for multiple days, only to have the email nodes suddenly lose all the HTML code within them to force a rebuild of the emails.   We have copied a journey and the email nodes are copied also but the content in them is blank.     Is this unique to our instance of AJO?  Are there best practice steps our team should be adopting to avoid these issues.   We've notice this more in the past month.  We are discussing making backups of everything because we've had this disappear on the day we were to deploy campaigns.   Teams have noticed this while on a MS Teams call with colleagues, which also points to stable connectivity.  

Is this a known issue? Or are there preferred/best practice steps/sequences when copying a journey that must be followed.  Looking for process solutions, as we already have tickets open with Adobe Support.
