Task filter lags

How do I fix the problem that when I filter tasks by a specific notebook with the IOS app, it can take up to 30 seconds to execute.

Hi.  How's your experience of Evernote otherwise?  Do searches return a full list of results more quickly than that?

Yes, otherwise it’s all good. 
 

For the filter, the lag is is before I choose a notebook. Once I choose filter and then « located in », it takes way too long to offer me the choices of notebooks. I only have a few notebooks and not an unreasonable amount of tasks.
