Avianca 4+

I have traveled with Avianca before but I do have to say that this time they went above and beyond my expectations. I had purchased my mom a first class ticket so she could be more comfortable to my total surprise they upgraded me to first class as well because they had an empty seat and they said so I could keep an eye on my mom! I am grateful and thankful for such great gesture

This is my third (and last) time flying with Avianca and let me tell you, all of my experiences have been extremely stressful. First of all, online check-in for international flights never works (idk if they do it on purpose to have you talk to them) and you always have to be earlier at the airport because of that (even the first time when I just had carry on luggage) second of all, last time I checked in with a live person he said that I needed to pay for my bag. I had paid for it when I purchased the ticket, very calmly I explained to him that I had paid for it already and showed him the receipt, he still said that I had to pay, only after requesting for his supervisor he confirmed the bag was paid and I was good to go (all this unnecessary issue took about 10 minutes). Now, today I’m trying to check in again and the app doesn't work!? Can’t believe they haven’t fixed this by now (it’s been around 4 years already) if this company really cares about customer service then focus first on fixing the very simple things, you need to understand people can’t be all day in front of a computer trying to complete a simple thing that’s checking in.

I started using this app in May 2019 on my iPhone and I loved it and enjoyed the airline and its professional employees. For some reason, starting this year Avianca has changed for the worse from customer service, and plane accommodation for less than 5 hours, and now the app has started acting up with problems logging in, failing to post my Lifemiles flights or it disappearing 2 weeks after my latest flight.
Currently, I cannot log into the app because it's saying: "Sorry this device cannot be considered safe and you will not be able to use the application."

This isn't making any sense because I never had a problem with it before plus I use a VPN and other protection from viruses etc. There's nothing on the site to address the problem and I'm not the only one. I'm not sure if they have anyone monitoring this app review. If they don't fix it, it will downgrade the outstanding past reviews it was known for great service and app. Please let's fix this problem.
