Better option would be to install Signal direct from their website. Scroll down under the ‘Danger Zone’ this apk is self-updating. https://signal.org/android/apk/
Just to know if this happens with other apps, how probable is it that /e/ can fix this types of issues? Is it better to seek for an workaround like with Signal or is it valuable for the /e/ team to get informed about this issues ?
Hello, I had today a person who bought an /e/ phone after I recommended her to do a few months ago who reported this problem to me. Good luck in fixing the backend of Apps, so that lambda users could enjoy fresh and updated apps. I gave the person the direct link to the apk (thanks @b3pio) and told her the problem was already known and fix was on the way.
Since I updated to version 0.9 of the /e/OS my signal app seems to update as expected again. The new Apps version seems to have solved it. I also had a couple of other programs stuck with the previous versions, they were updated correctly as well.
