Users who have already applied the temporary fix should be able to update the apps, however if this causes the issue to return, you should repeat the instructions in the original thread to uninstall them again. If updating does not cause the issue to return, you should be able to safely re-enable automatic updates.
If anyone continues to have issues after updating both apps, please let me know so that I can update the post with details of the issue.

One user has reported issues with the play store itself crashing when attempting to download the updates.
A small number of users have reported the issues persisting after updating both affected apps. I would guess that for whatever reason the new (fixed) version isn't yet available to these users, however I would welcome feedback from anyone who may know more.
If anyone has any idea how these users can sort the issues out, please let me know so that I can update this post with details.
If you are experiencing any issues after trying the above fix, please let me know (even if it is already listed above), and include as much detail as you can (what is happening, do any errors appear, etc.).
None of the issues appear to make the problem any worse or reintroduce solved problems.
A small number of people have been experiencing issues getting the update to download. Unfortunately I am not aware of a solution to that particular issue. This is the first report I've seen about Google play crashing, I will keep on the look out for more information regarding that particular issue.
I've not been able to access new emails since yesterday morning. Noticed further issues with apps last night, including my banking and opening links from Instagram. I have tried to update both apps mentioned, but cannot do so as my playstore shows they both updated yesterday
