Having the same issue..if I get an email from a forum such as this one, the link embedded inside the email will be blue and "clickable". However, if I receive 2 or more emails from the forum, it will group them together as one message and the links will be grayed out and "unclickable"
I have found that sometimes marking it as unread and reopening it again SOMETIMES allows the link to work again.
I would also like to know how to ungroup messages from the same sender
Here's what I do...when I get an email about a thread here being updated and I've already gotten one...the gmail app groups like emails together in a thread similar to gmail.com.
At the top of the email should be a tab that says # read messages (# is the number you've actually received).
Click that tab and it should expand to show the subjects.
Click on the very top one.
The link should be clickable there, but isn't in the rest...
Hope this helps! Took me a while to figure out myself, but sure saves time and hassle. If you're having issues and have only received one such email, I'm not sure what to say.
This may not be acceptable to everyone but I've found that the limitations in the default "gmail" application to be problematic. I use it simply to check email as a result of a notification. When I want to handle more complex tasks, I simply login to gmail.com. (Have it set as a favorite on my browser(s).)
Handling attachments and unscrambling complicated email threads is easier from the website, imo. Of course, if I'm sitting at my desk (as I usually am), I use my desktop PC to handle the email (and google calendar.) For someone with fat thumbs and bad eyes, it's much easier.
I really dont know if one has anything to do with the other, but i have noticed all day that and facebook links i access through gmail lead nowhere. i can open gmail either app or through browser, for instance ill have an email indicating a message on facebook. ill click the link and it opens the browser with a blank screen. try refreshing it still nothing.
EDIT: it has to be something with facebook. i purposely subscribed to some hot topics here and am having no problem at all accessing this site through the links provided in the email.
