1Password crash v. 7.9.1 on IOS [update to 7.9.2 or update iOS if at all possible]

I also have discovered that the recent software update of 1Password 7.9.1 crashes on my iPhone 6 running iOS 12.5.5 (the latest possible iOS on this phone).
Fortunately I have IPassword on my Imac that still works - but have now created a pdf copy as I am feeling very vulnerable to the vagaries of software changes leaving you high and dry!
Hopefully a fix can come soon.
