I also should add that I started to experience issues with Whatsapp as i updated end of May, start of June. Crashing (kind of a lot), notifications do not work at all anymore compared to "just works" the weeks / months before. No other issues I've noticed so far.
I have Whatsapp installed from their website.
To note, this broken behaviour today is the exact behaviour of an up-to-date Whatsapp install January - March with Google Play services disabled after setup (with Google Play Services on at the moment of setup when it used to recognize GPS availability)
Has a reinstall yielded fruitful results for anyone,
in terms of no issues with notifications, crashing, other issues (without Google Play Services)?
