This is such a simple fix that many other cloud providers have implemented. Let's get two things straight, LastPass engineers are not "hard at work", they are horrendous. They close cases without even attempting to resolve. It's no surprise 2 years later they have not addressed the issue.
To fix the issue, they just have to enable "native browser" authentication. The LastPass app is using it's own browser to do the authentication. That browser does not pass details about the device to conditional access policies. Native browsers on an iOS device such as Safari, and Edge, do. So if you have a Conditional Access policy based on device compliance, LastPass will be blocked. LastPass has to redirect the authentication to the native browser; SIMPLE. They need to do this for GotoAssist as well.
