What is the difference between:

Option 1: Since then, I have been constantly working towards improving.

Option 2: Since then, I have constantly been working towards improving.

As per Grammarly, it says there is an adverb placement issue with option 1, I don't see any issue. Plus I find this option easy to read.

Plus I find option 2 awkward to read.

Are both options correct or one of both of them are wrong?

Verbal experts - Could you please help?

_________________

No problem with either version.
Constantly is an adverb modifying have been working in both the cases.

Thanks for your reply. So an adverbial modifier can be placed anywhere, is it? Are there any exceptions?
_________________

In this case, there are two actions:
i) working
ii) improving

In the versions you quoted, constantly modifies working.

If you place constantly at the end, it will modify improving.


Adverbs modify the nearest action.

Do let me know Manish if it is clear.
Happy to elaborate.

Thanks, it is clear.
