Re android app and up to date version (new green logo)

Ive noted that following the update to the green logo app that the ypdating of rhe map has become particularly lethargic. Infact at points downright reluctant to update or change between various map options (wayfarer, OS etc). This is regardless of whether I have a poor wifi signal or not. Just tried it sat next to my router and no joy.

Where before I could use the app to quickly plot out a route now its somewhat easier (sometimes) to do it on the website. 

Is there a known change to the app/ use philosophy which might cause this mapping reluctancy? I seem to remember seeing a comment in a previous thread about possible times of day that might affect maps due to updates however for me it appears to be anytime.

As an update the only way I seem to get amore reliable app map operability is to force it to close, clear the cache and then start the app again.

Regards
