Hiya @Falco
Hmmm ??? That is going to upset a lot of users then that maybe using the app under android 7.1.1 and
will render them unable to install updates.
I have read about the new certificate databases and have seen some minor issues regarding this already (not discourse issues).
Bumping up the SDK Tag in the app isnt always a good move especially with android games as users then start to scream at game devs including myself 
I also have an Android 7.0 Tablet however this 'Bump" will render that not applicable to use/install the app also as im on the highest release (apparently) the tablet can support from the manufacturers and its only a year old (not the o/s).
All i suggest is you think this through as it wont be good for devices out there where the O/S cant be updated even if play store/play services does keep getting updated.
