Sync is a perfectly fine app for me. I tried all other apps and nowhere near to sync. I don't even have ads on the free version as I am using dns ad blocker. The moment one time payment for removing ads is out(it is coming), I will buy it. Or I will donate to dev in some other way as I am not a fan of subscriptions.
I used sync for reddit for so many years and paid $2... I just paid the ad removal price on the new app right away. Even if the app ends up sucking, i want to support the dev for all the previous work
I will definitely consider switching to FOSS option though
Yeah they are empty on my phone too, and I've never used any DNS-adblocking on my home network. I suspect it might be because whatever ad system Sync uses currently just doesn't have any ads for my country, but I don't actually know.
It's the same in the US (for me at least) also, either it's not working just yet, or it's just a placeholder for now, you never know with pre-release apps.
I've tried different reddit third party apps for months at a time, and I've got to say, Sync is probably the best app I have used in terms of designs and fluidity.
