I had used your app for quite some time with no problems at all from a linux box using Ubuntu 18.04 and either chrome or Firefox (mainly). Thanks for making my social media life so much easier by making a computer interface. Much appreciated :)
The only additions I could suggest would be the ability to post albums and to edit headers after posting as often one has to add extra hash tags due to info from responders.
I then advised a friend using a mac to try it. He had great fun for 2-3 days!! Then overnight on 26th to 27th Feb, here in Melbourne Australia, it stopped being useful for uploading to instagram as it wasn't possible to enter in the heading and hash tag information data which you add just before posting. I did google search and could find nothing about it but read that changing user-agent might allow one to do the same thing. So thought I would try that on my home computer before trying on my friends mac. This resulted in my version of the addon getting the same problem using your add-on either in Chrome or Firefox. I updated both just in case that might be the problem .. Still no workable solution!
Any help you can give me solving this problem would be very much appreciated :):)
Thanks very much :):)
