I have recently resorted to using IE as my browser after Chrome caused several issues but IE is causing typing gremlins on here for me and silly things like it won't allow quotes to appear when replying to a post but it will, sometimes after a couple of stabs using the multi quote option, so I for one do sympathize with you over your posting gremlins. I'm putting a lot of it down to Windows 10 (installed after the change from Chrome) that clearly is set up to be more rewarding to Microsoft than its customers...... albeit some features are a step forward, but not enough to stop me pulling out the last of my hair! So us mods have the same/similar issues. Have tried other browsers too but the poor old Dell I use that is getting near its 10th birthday is in worse shape than its owner, I suspect.
Have tried using the tapatalk app on your phone? Personally, on the S3 I currently use, I found the full version of the forum is more user friendly.
But shortly dumping all of that for the fruity option
