Just upgraded to a new phone running Nougat and apparently this issue "Server error. IOException Chain validation failed" has been ongoing since late last year, so that's cool. Any word on if the developers plan on ever fixing this? Not a huge fan of the mobile site and I'm gonna go ahead and assume asking for access via Tapatalk will receive many negcats.

 

Yep, been broken since Nougat came out. I've just been using the (supposedly not supported) mobile site. Would have figured 9 months would be long enough to fix it, but IB strikes again.
