The reason why 'range' period is needed is that API.getSuggestedValuesForSegment calls Live.getLastVisitsDetails for last 60 days to get typical values from visits log for suggestions:

Maybe acceptable solution here would be to fetch suggestions for 'month' period? Then 'range' period could be still locked and suggestions would work.

@adaqus maybe we could make it configurable and it should depend on the periods that are enabled and available in API? in this particular case "last90" would be best to use if possible because this is segment processing configuration.

I think it is plausible solution.

For anyone who finds this in the future: maybe this could be adjusted basing on current configuration of periods availability. We found out what we need and we got it working without any major changes, but this issue may come up for some users.

We could change the time to look back based on enabled periods, that should be doable.

@mgonera what did you find out and how did you get it working?

I found out that the reason for suggestions failing was periods_API=range disabled. We simply enabled it back.

Maybe acceptable solution here would be to fetch suggestions for 'month' period?

@adaqus sounds good, or maybe even year period?

Pull request is very welcome :-)
